5 1.0 PURPOSE STANDARD OPERATING GUIDELINE RADIOLOGICAL INFORMATION AND CONTROL This Standard Operating Guideline (SOG) provides guidance for radiation protection, monitoring, detection, and documentation. It also includes guidance for the operation of equipment designated for use within the county s Radiological Emergency Preparedness (REP) program (i.e. dosimeters, portal monitors, etc.). 2.0 SCOPE This SOG provides guidelines for REVC volunteers participating in response and recovery activities related to a radiological emergency at a nuclear power electrical generation site. The overarching goal of this SOG is to provide methods, limits, controls, and techniques that will maintain the volunteer s exposure As Low As Reasonably Achievable. 3.0 REFERENCES & SOURCE DOCUMENTS North Carolina Radiological Emergency Response Plan, North Carolina Emergency Operations Plan, Annex B, Appendix 8 (January 2012) Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, NUREG-0654/FEMA-REP-1, Rev. 1 (November 1980).

6 4.0 GLOSSARY / ABBREVIATIONS / DEFINITIONS AS LOW AS REASONABLY ACHIEVABLE (ALARA): Radiation protection principle in which every reasonable effort to maintain exposures to ionizing radiation as far below EPA recommended dose limits whenever possible. CDE: Committed Dose Equivalent (organ exposure) CPM: Counts per Minute (used for contamination monitoring) DIRECT READING DOSIMETER (DRD): Personal radiation monitoring device that indicates gamma radiation exposure which can be read in the field. Requires an auxiliary charging device (dosimeter charger) (sometimes referred to as SRPD or self reading pocket dosimeter). EMERGENCY WORKER (EW): an individual who has an essential mission to protect the health and safety of the public and could be exposed to ionizing radiation from the plume or its deposition. This includes volunteers within REVC. EMS: Emergency Medical Services EOC: Emergency Operations Center EPZ: 10-mile Emergency Planning Zone around a nuclear power plant INTERMEDIATE PHASE: The period beginning after the utility has verified that the release has been terminated. Reliable environmental measurements are available for use as a basis for decisions on additional protective actions. It extends until these additional protective actions are terminated. This phase may overlap the late phase and may last from weeks to many months. The phase encompasses REP post-plume activities associated with both ingestion and relocation. LATE PHASE: The period beginning when recovery action designed to reduce radiation levels in the environment to acceptable levels for unrestricted use are commenced, and ending when all recovery actions have been completed. This period may extend from months to years. REP post-plume activities associated with return and recovery occur during the late phase. MILLIREM (mrem): 1/1,000 of a REM. MONITORING PAD: An easily removed disposable floor cover (paper or polyethylene) used during individual contamination monitoring. May feature multiple tacky (sticky) side-up layers which can be removed as dirt, dust, or contamination build up. NCEM: North Carolina Emergency Management NCRPS: North Carolina Radiation Protection Section ORO: Off-site Response Organization PAG: Protective Action Guide. The projected dose to an individual in the general population that warrants the implementation of protective action. PERMANENT RECORD DOSIMETER (PRD): Personal radiation monitoring device that indicates beta and gamma radiation exposure and must be read in a laboratory (previously called TLD or Thermoluminescent Dosimeter). 2

7 GLOSSARY / ABBREVIATIONS / DEFINITIONS, continued PLUME PHASE (also Early or Emergency): The period at the beginning of the a nuclear incident when immediate decisions for effective use of protective actions are required and must therefore usually be based primarily on the status of the nuclear power plant and the prognosis for worsening conditions. This phase lasts hours to several days and ends when the radioactive release ends. PORTAL MONITOR: A portable device used to quickly measure contamination on ambulatory evacuees. POTASSIUM IODIDE (KI): Potassium Iodide tablets or solution indicated for prevention of radioactive iodine uptake by the thyroid. RADIOLOGICAL CONTROL: All methods, limits, controls, and techniques used to maintain radiation doses As Low As Reasonably Achievable (ALARA). RCCC: Reception Center and Congregate Care REVC: Radiological Emergency Volunteer Corps ROENTGEN EQUIVALENT MAN (REM): The unit of dose for ionizing radiation that produces biological effect as a unit of absorbed dose of ordinary x-rays. A unit of dose for measuring the amount of ionizing radiation energy absorbed by biological tissue. ROENTGEN (R): The unit of gamma or x-ray exposure in air. For the purpose of this guidance, one R of exposure (as read on a dosimeter) is approximately equal to one REM of whole-body external dose. RSO: Radiation Safety Officer SERT: State Emergency Response Team SRPD: Self Reading Pocket Dosimeter (also referred to as direct read dosimeter) STEP OFF PAD (SOP): A durable floor cover (lexan, paper, or polyethylene) which serves as the physical boundary between clean and contaminated areas (cold and warm zones). TEDE: Total Effective Dose Equivalent. The sum of the deep dose equivalent (for external exposures) and for committed effective dose equivalent (for internal exposures). TOREV: Team of Radiological Emergency Volunteers 5.0 CONCEPT OF OPERATIONS 5.1 Direction and Control Radiological dose control is the responsibility of every volunteer engaged in response and recovery activities as a result of a nuclear power electrical generation site emergency. Potential response sites include; Brunswick Nuclear Plant [2 Units-Boiling Water Reactor (BWR) design] 3

8 Catawba Nuclear Station (North Carolina response only) [2 Units-Pressurized Water Reactor (PWR) design] Harris Nuclear Plant [1 Unit-Pressurized Water Reactor (PWR) design] McGuire Nuclear Station [2 Units-Pressurized Water Reactor (PWR) design] County Emergency Management is responsible for: a. Ensuring that the methods, limits, controls, and techniques contained in this Standard Operating Guideline meet applicable regulations, guidelines, manufacturer s recommendations, and industry standards. Providing direction and control that reflects due consideration for As Low As Reasonably Achievable (ALARA) principles while remaining focused on life safety, incident stabilization, and protection of critical infrastructure and the environment. b. Exercising authority to permit specialized emergency workers to exceed administrative dose limits to ensure a prompt, coordinated response to the affected nuclear site to support critical life-saving, law enforcement, and accident mitigation activities. c. Identifying a Radiation Safety Officer (RSO) who will provide technical support within the Emergency Operation Center in cooperation with the North Carolina Radiation Protection Section NC Radiation Protection Section (NCRPS) will provide technical guidance on radiation control activities. Radiation Protection Section has statewide responsibility for coordination of radiological monitoring, decontamination, and waste storage and disposal REVC Coordinator is responsible for: a. Ensuring that the methods, limits, controls, and techniques contained in this Standard Operating Guideline are understood by the responding volunteers using the training formats laid out in the REVC Training SOG. NOTE: NOTE: REVC volunteers are considered emergency workers when responding to a nuclear event. They will fall under the authority and direction of the established command and control positions within the response organization. All volunteers reserve the right to refuse any assignment for any reason. 4

9 6.0 EXPOSURE CONTROL 6.1 Dose limits, as provided in EPA 400-R for emergency workers, apply only during the Emergency Phase. The emergency phase ends when (1) the utility determines that the release has terminated, and (2) the responsible Off-site Response Organization has determined that public safety is ensured by appropriate protective actions in accordance with applicable Protective Action Guidelines and that valuable property has been protected. This would include the Re-entry phase of the event. 6.2 Permanent Record Dosimeters (PRD), Direct Reading Dosimeters (DRD), and Personal Radiation Exposure Record Forms (see Attachment 1) are utilized to control and document emergency worker radiation exposures. 6.3 The radioprotective drug Potassium Iodide (KI) has been adopted for use in blocking the uptake of radioactive iodine by the thyroid gland for emergency workers and the public. The Total Effective Dose Equivalent calculation for emergency workers who have ingested potassium iodide does not include the contribution from thyroid dose due to inhalation of radioiodine, because that contribution will be minimal if potassium iodide is administered prior to exposure. 6.4 Emergency workers will be limited to non-pregnant adults (at least 18 years old). 6.5 Dose Limits Dose limits during the EMERGENCY PHASE (PLUME PHASE) Exposure control practices during the Emergency Phase are established to ensure that the accumulative radiation dose to emergency workers and the general public remain As Low As Reasonably Achievable, ALARA and do not exceed the following Environmental Protection Agency limits 1 as measured by a direct reading dosimeter: a. 5 R for any emergency activities; b. 10 R for protecting valuable property when lower dose is not practicable (feasible); c. 25 R for life-saving activities or protection of large populations when lower dose is not practicable; and d. Greater than 25 R for life-saving activities or protection of large populations where only emergency workers who volunteer for higher doses are allowed and only if they have been made fully aware of the risks. 1 EPA-400-R

10 NOTE: Emergency workers must have approval to exceed the 5 R dose limit (See item below) Until evacuation of the general public is complete, monitoring of emergency worker dose is based only on gamma radiation exposure as measured by a direct reading dosimeter without regard to additional dose received from inhalation AND beta exposure. Emergency workers entering the 10 Mile EPZ MAY be assigned a lower Administrative Dose Limit until the PRD can be read and exposure for the person is verified accurate Emergency workers must receive approval from the Most Senior official in the EOC or designee prior to exceeding the 5 R dose limit, or an Administrative Limit (if imposed) Dose Limit extensions during EMERGENCY PHASE (PLUME PHASE) During an event a critical mission may occur that requires a higher exposure limit. The following guidance will be used to ensure the health and safety of the individual is maintained, but provide extra-ordinary means to save a life or protect critical infrastructure (use Attachment 15 as needed). Note: Use the Quick Reference Chart for Dose Exposure to Individual if dose rates in area are known. This will provide stay times for individuals to ensure exposure limits are not exceeded. Note: The most senior official for the responding county approves all exposure limits that exceed the 5 Rem Total Effective Dose Equivalent State Turn-back value Once the request is made known, the County Health Director, Emergency Operation Center Director, and/or Radiation Safety Officer would discuss the need for increased exposure to the individual(s) Using risk assessment strategies compare the mission requirements to additional exposure to individual and the potential health risks. All avenues should be addressed prior to the approval of higher exposure limits to emergency workers. These include; Comparing the requested mission to the increased health risks to the individual(s) Using multiple emergency workers for the mission allowing exposure to remain below the 5 Rem Total Effective Dose Equivalent limit The use of time, distance and shielding to provide adequate exposure control during the mission The most senior official for the county APPROVES or DISAPPROVES the extension based on the above decisions. 6

11 6.5.6 Once the mission has been completed, remove the individual from the restricted/exposure area and complete the Emergency Exposure Authorization Form. Note: Since time can be a factor in emergency exposure approval verses mission urgency; telecom, computer processing or other means can be used to expedite the process. Note: Dose to emergency workers is treated as a once-in-a-lifetime exposure and is not added to occupational radiation exposure accumulated under non-emergency conditions Dose Limits during the INTERMEDIATE PHASE and LATE PHASE (POST- PLUME PHASE) Exposure control practices during the Intermediate and Late Phases are controlled according to dose limits for occupational exposure, as identified in 15A NCAC or 10CFR20 3, whichever is more restrictive (Generally 5 R per year for a non-pregnant adult) Categories of Emergency Workers Emergency worker categories are based on the potential relative risk of personal exposure for assigned tasks, and provide the minimum dosimetry required for that position: a. CATEGORY 1 Emergency Worker Category 1 is defined as emergency workers who are assigned to operate inside the 10-mile EPZ during the Emergency Phase of an accident, or could potentially work in a high radiation exposure area greater than 0.1 R/hr (> 100 mr/hr). Minimum Dosimetry: One (1) permanent record dosimeter and one (1) high-range (0-20R) direct reading dosimeter. 2 NC Administrative Code 15A NCAC Standards for Protection Against Radiation 3 NRC Regulations (10CFR) Part 20 Standards for Protection Against Radiation 7

12 b. CATEGORY 2 Emergency Worker Category 2 is defined as emergency workers who could be exposed to ionizing radiation outside the 10-mile Emergency Planning Zone during the Emergency Phase of an accident, or could potentially work inside the 10-mile during the Intermediate or Late Phases (Post-Plume Phase) provided radiation levels will not exceed 0.1 R/hr (< 100 mr/hr). Minimum Dosimetry: One (1) permanent record dosimeter and EITHER one (1) high-range (0-20R) direct reading dosimeter or one (1) low-range (0-200 mr) direct reading dosimeter In the event emergency workers are assigned to work together as a team in close proximity to each other, a single direct reading dosimeter may be worn by a designated team member. All workers must still wear a permanent record dosimeter Minimum dosimetry requirements and Administrative Dose Limits for emergency workers may be modified by County or State Emergency Management based on assignment and ongoing release assessment Permanent record dosimeters will be submitted to a contract laboratory to be read. Dose levels will be analyzed by Radiation Protection Section, and an Occupational Dose Record (see Attachment 2) form will be completed for each emergency worker. 7.0 PERSONAL RADIATION EXPOSURE RECORD CARDS 7.1 Personal Radiation Exposure Record Cards (see Attachment 1) are provided to each emergency worker when dosimetry or potassium iodide is issued. 7.2 The card serves is a record of accumulated radiation dose as measured using a direct reading dosimeter. It also capture s direct reading dosimeter and permanent record dosimeter serial numbers, potassium iodide lot number, and the date and time of potassium iodide ingestion. It also provides quick reference information for emergency workers. 7.3 Emergency workers will maintain their card for the duration of the incident. If the emergency worker runs out of room to record readings, additional cards may be stapled to the original. 7.4 Completed cards will be submitted to the County Emergency Operation Center after the incident is terminated, or if the emergency worker will not be returning for another operational period. 8

13 8.0 PERMANENT RECORD DOSIMETERS 8.1 County Emergency Management will distribute permanent record dosimeters to emergency workers. Permanent record dosimeters may be pre-distributed with equipment caches or deployed from a single storage location after an emergency is declared. 8.2 Permanent record dosimeters and all Dosimeter Logs form (see Attachment 3) documenting who they were assigned to will be returned to the County Emergency Management at the termination of the event. 8.3 Emergency workers issued a permanent record dosimeter shall: Indicate the permanent record dosimeter serial number on their Personal Radiation Exposure Record Card Wear the permanent record dosimeter on the front of the body between the neck and the waist (see Attachment 4) Wear the permanent record dosimeter on the first layer of clothing, prior to donning personal protective equipment (personal protective equipment, i.e. Tyvek coveralls, bunker gear) Wear the permanent record dosimeter with the front side facing away from the body. The county name and serial number is printed on the front side. The permanent record dosimeter should be secured to clothing or a lanyard with the spring-loaded clip (or equivalent) in such a manner to secure it during expected work activities Emergency workers will be assigned a single permanent record dosimeter for the duration of the incident or until a new PRD is issued at the guidance of Radiation Protection Section. Emergency workers WILL NOT swap or otherwise transfer an assigned permanent record dosimeter to another worker. 8.4 SPECIAL CONSIDERATIONS: The permanent record dosimeter and direct reading dosimeter should be worn close together to allow the same exposure to be received by both devices. However, the permanent record dosimeter will remain under the personal protective equipment, and the direct reading dosimeter will remain outside the personal protective equipment for field readings. Actual permanent record dosimeters will not be used during exercises, drills, or training. Emergency workers should wear simulated permanent record dosimeters for these activities (e.g., clothespin, paper simulation, cardboard, etc.). 9

14 9.0 DIRECT READING DOSIMETERS 9.1 County Emergency Management will distribute direct reading dosimeters to emergency workers. Direct reading dosimeters may be pre-distributed with equipment caches or deployed from a single storage location after an emergency is declared. 9.2 Direct reading dosimeters and all records (forms) documenting who they were assigned to will be returned to the County Emergency Management at the termination of the event. 9.3 Direct reading dosimeters must be re-zeroed prior to use: For zeroing (charging) the pen shaped, carbon fiber ion chamber style of direct reading dosimeters, see Attachment 5. NOTE: A CD V-750 Model 5/6, Model 909 or equivalent dosimeter charger is required. 9.4 Direct reading dosimeters will be read every 15 to 30 minutes, unless otherwise directed, based on the intensity of the radiation field the emergency worker is in. A higher intensity radiation field will require the emergency worker to check more frequently (at least every 15 minutes) to ensure they do not exceed dose limits. 9.5 Emergency workers issued a direct reading dosimeter shall: Indicate the dosimeter type (i.e. ArrowTech 730, 0-20R, or High Range), the direct reading dosimeter serial number, and the initial reading on their Personal Radiation Exposure Record Card Wear the direct reading dosimeter on the front of the body between the neck and the waist (see Attachment 4) Secure the direct reading dosimeter outside of clothing and personal protective equipment, to allow easy access for reading the device while in the field The direct reading dosimeter should be attached with the spring-loaded clip (or equivalent) in such a manner to secure the direct reading dosimeter during normal work activities Indicate any readings above zero on the Personal Radiation Exposure Record Card At the end of the operational period (shift): Indicate the final reading on the Personal Radiation Exposure Record Card. Subtract the initial reading from the final reading, and record the result under the Reading Exposure R column. This represents the emergency worker s accumulated dose for a single operational period. 10

15 Add all values listed under Reading Exposure R and record the result under the Total Exposure R column. This represents the emergency worker s accumulated dose for the entire incident. Ensure that accumulated dose is within exposure limits printed on card. Notify supervisor or County Emergency Operation Center if accumulated dose is approaching or has exceeded exposure limits. Return the direct reading dosimeters to the equipment officer. 9.6 SPECIAL CONSIDERATIONS: A direct reading dosimeter that is not zeroed can be used as long as its current reading is listed as the initial value on the Start row of the Personal Radiation Exposure Record Card. If a direct reading dosimeter behaves erratically when charging 4 or on startup 5 DO NOT use the device. There should be sufficient supplies to replace the dosimeter or a single direct reading dosimeters readings may be shared for emergency workers operating in close proximity to each other. Direct reading dosimeters may be reassigned as needed during an incident as long as the exposure for the first worker is documented on the Personal Radiation Exposure Record Card is documented prior to reassigning the device. CAUTION: If a direct reading dosimeter goes off-scale 5 or a HIGH DOSE or HIGH RATE alarm activates 6, leave the area immediately. Notify a supervisor, record the time it was noticed, identify others in the area that may have received the same dose, re-zero (charge) the dosimeter and await further instructions. DO NOT go back into the area without authorization from your supervisor. Emergency workers will communicate any exposure to their supervisor POTASSIUM IODIDE (KI) 10.1 The radioprotective drug Potassium Iodide (KI) has been adopted for use in blocking the uptake of radioactive iodine by the thyroid gland It is the responsibility of County/State Public Health Director, or the Radiation Protection Section designee, to approve the administration of potassium iodide to emergency workers. 4 For pen style direct reading dosimeters 5 For electronic dosimeters 11

16 10.3 Potassium Iodide Distribution a. It is the responsibility of the County Public Health Department, in cooperation with County Emergency Management, to ensure that potassium iodide is delivered to designated emergency worker distribution sites (Staging Area, County Emergency Operation Center, etc.). b. The County EOC will provide each emergency worker with 130 mg of potassium iodide, and the potassium iodide Information sheet (see Attachment 6) or equivalent. c. The Radiation Safety Officer, or their designee, will use a potassium iodide Log form (see Attachment 7) or equivalent to capture each emergency worker s Name, Agency, Social Security Number, Assignment, and potassium iodide Lot Number. If the potassium iodide is to be ingested immediately, the date and time is recorded; otherwise the field is left blank. d. Potassium iodide Log forms will be submitted to the County Public Health Director. e. Emergency workers will be cautioned not to ingest the potassium iodide until instructed to do so by their supervisor, or the County Emergency Operation Center Potassium Iodide Dosage a. Potassium Iodide is supplied in a foil strip, cross-scored tablet, 65 mg. b. The typical dose regimen is 130 mg per day, for ten (10) days, unless otherwise directed by County/State Public Health. c. Self-administration of potassium iodide, after permission is given, is voluntary for emergency workers Potassium Iodide Administration a. It is the responsibility of County/State Public Health Director, or the Radiation Protection Section designee, to approve the administration of potassium iodide to emergency workers. b. The recommendation will be based on the suspected, projected, or confirmed presence of radioactive iodine in an accidental release. Potassium Iodide will be recommended when any thyroid exposure (not a whole body exposure) is reasonably suspected, projected, or confirmed. There is no protective action guideline dose threshold that must be reached, only the possible or actual presence of radioactive iodine. c. When permission is given, and unless otherwise directed, emergency workers will take 130 mg of KI. 12

17 d. Various agencies involved with specialized emergency worker responsibilities can be granted standing permission to self-administer 130 mg of potassium iodide in the event of a radiological release, prior to entering the plume or affected areas, if it is not practical to contact the County Emergency Operation Center. Specialized emergency workers are those providing onsite or near-site critical life-saving, law enforcement, and accident mitigation activities. These specialized emergency workers include: Agencies involved with waterway warning on Lake Norman Law enforcement officers involved in onsite hostile action suppression (including Specialized Weapons and Tactics (SWAT) teams, bomb squads, canine (K9) teams) Fire department personnel involved in onsite fire suppression, medical emergency response, or decontamination operations Emergency Medical Service personnel involved in onsite medical emergency response (includes tactical medics embedded with Specialized Weapons and Tactics teams) Incident management personnel coordinating operations from an onsite or near-site Incident Command Post Mutual aid personnel Emergency workers assigned to support State field monitoring teams 10.6 Potassium Iodide Side Effects Potential side of effects of potassium iodide include: a. Intestinal upset. b. Allergic reaction (possibly severe). c. Rashes. d. Inflammation of the salivary glands. e. Iodism (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, stomach upset, and diarrhea). f. Rarely may cause over-activity, under-activity, or enlargement of the thyroid gland (goiter). g. Serious allergic reaction may include: Fever and joint pain. Swelling of parts of face and body. Occasional severe shortness of breath (WARNING Shortness of breath requires immediate medical attention) Adverse health effects are more likely if you (1) take a higher than recommended dose of potassium iodide, (2) take the drug for several days, or (3) have pre-existing thyroid disease. 13

18 11.0 CONTAMINATION CONTROL and DETECTION 11.1 Contamination control includes the methods, limits, controls, and techniques used to limit the spread of loose radioactive material released during a nuclear power plant accident All evacuees and emergency workers who were within the Emergency Planning Zone after a radiation release has occurred should have a Whole Body Survey for contamination (see Attachment 8). NOTE: Thyroid monitoring (see Attachment 8) is only required if requested by the County Emergency Operation Center An Evacuee/Emergency Worker Contamination Record form (see Attachment 9) should be completed for any person found to be contaminated Background Level Background radiation levels are determined by setting the instrument so it displays in Counts per Minute and observing the readings for 30 to 60 seconds with the Geiger-Mueller pancake detector uncovered. Note the highest and lowest observed values, and determine an average by dividing the sum of the highest and lowest value by 2. BACKGROUND = (HIGHEST CPM 1 MIN + LOWEST CPM 1 MIN ) 2 NOTE: Normal background radiation levels are approximately 60 Counts per Minute in most areas of North Carolina Record background radiation readings on a Background Placard (see Attachment 10) posted in a conspicuous location. Update the form at least once a shift, or more often if needed If the background exceeds 100 Counts per Minute, contact the Radiation Safety Officer for the facility, or the County Emergency Operation Center, to determine if area is acceptable for continued use Action Level Any person, property, vehicle, apparatus, or equipment with surface contamination levels found to exceed the Action Level (greater than or equal to 300 Counts per Minute (CPM) using a Ludlum Model 26 or equivalent meter) is considered contaminated, and must be reported to the Emergency Operation Center Radiation Safety Officer. Anything with contamination levels found to be below the Action Level are considered uncontaminated (clean). 14

19 11.6 Handheld Contamination Survey Meters A survey instrument equipped with a pancake detector will be used for contamination surveys (frisking ) Emergency workers will refer to instrument-specific Setup, Operation, and Precautions guidance provided by Attachment 11 for operation of contamination survey instruments currently in use Contamination levels should be recorded in units of Counts per Minute (CPM) when using a Ludlum Model 26 or equivalent meter Portal Monitors Portable portal monitors are utilized to rapidly survey large numbers of evacuees and are factory programmed to alarm upon detection of a 1.0 µci Cs 137 or greater source in a 10 µr/hr background field, in accordance with FEMA standards 6. Action Level and other operational parameters are stored in non-volatile memory that does not require battery backup The portal monitors in use report contamination levels in Counts per Minute (for the Ludlum Model 52) or Counts per 0.2 Seconds (for the Ludlum Model ), however they are used only to indicate the presence of significant contamination Emergency workers will refer to instrument-specific Setup, Operation, and Precautions guidance provided by Attachment 12 for operation of portable radiation portal monitors currently in use Emergency workers will record the location of the contamination alarm as indicated on the portal monitor on an Evacuee/Emergency Worker Portal Monitor Card (see Attachment 13), but unless otherwise instructed are not required to document the level of contamination. NOTE: Portal monitors may be connected to a printer via RS-232 serial cable to automatically print the results of a contamination alarm (see Attachment 13). This receipt may be used in lieu of an Evacuee/Emergency Worker Portal Monitor Card. NOTE: Portal monitors are used as a Go, no Go test for contamination. For this reason the portal monitors are not required to have an annual calibration performed Personal Protective Equipment Specific Personal Protective Equipment (PPE) for emergency workers is recommended based on (1) an emergency worker s role and specific tasks, and (2) the risk of contamination Personal protective equipment can protect against internal contamination, external contamination (via inhalation, ingestion, absorption through open wounds), and other physical hazards (e.g., debris, fire/heat, or chemicals). 6 FEMA-REP-21 15

20 Personal protective equipment cannot protect against exposure from high energy, highly penetrating forms of ionizing radiation associated with most radiation emergencies Attachment 14 includes the recommended personal protective equipment for emergency workers based on the emergency worker s role and specific tasks, and relative risk of contamination Attachment 14 provides donning (dressing) and doffing (undressing) instructions that should be followed by emergency workers required to wear personal protective equipment. It is recommended that someone read the step-by-step instructions to emergency workers as they don and doff their personal protective equipment. NOTE: Instructions are NOT provided for donning or doffing of firefighter bunker gear. It is assumed that individuals will already have a working knowledge of this process Soiled/used personal protective equipment should be double-bagged and secured as contaminated solid waste until it can be removed. NOTE: Agencies may use different brands and styles of attire to meet or exceed the personal protective equipment guidance provided. Donning and doffing procedures may need to be modified to accommodate these differences Contamination Control Practices for Emergency Workers Emergency workers should take care not to rub their own exposed skin with potentially contaminated hands Restrict access to all papered/plastic walkways, monitoring, and decontamination areas until they have been surveyed and determined to be uncontaminated Keep all areas of emergency facilities clean, orderly, and contamination free to the extent practicable during operations Emergency workers should shower and change clothes as soon as practicable (feasible), even if found not to be contaminated Contamination Control for Reception Centers Treatment, triage, and transport of contaminated ill or injured evacuees and emergency workers will be provided by County Emergency Medical Services and local agreement hospitals or medical centers in accordance with Emergency Medical System Treatment Protocols and standard operating guidelines Evacuees and emergency workers who are monitored and found NOT to be contaminated will be advised to bathe and change clothes at their convenience within three (3) days. This is achieved through posting signs and/or providing handouts. 16

21 Evacuees and emergency workers who are (1) injured, or (2) suspected to have suffered a severe radiation exposure (> 25 R), will be immediately evaluated by medical personnel at the Reception Center, as directed by the Emergency Operation Center Radiation Safety Officer Care should be taken not to spread contamination to uncontaminated areas of the body, wounds, eyes, or body orifices (mouth, nose, ears) Decontaminate areas of highest contamination first Avoid decontamination techniques or duration that results in abrading or reddening of the skin, which could result in internal contamination. Immediately discontinue decontamination efforts if abrasion or reddening is observed, and notify the Emergency Operation Center Radiation Safety Officer Use lukewarm 7 water for washing to reduce the possibility of contamination entering the body through opened pores of the skin Instruct contaminated individuals to take care removing clothing in a manner that prevents the spread of contamination. This includes: Remove contaminated clothing without shaking or brushing; If possible, roll clothing as it is removed so contamination is trapped inside; Placing removed clothing and property into bags and sealing Collect, identify, and secure clothing and personal belongings so they may be cleaned and returned to the owner. This includes: Indicate property owner ID on all bags through use of sequentially numbered tags or labels (i.e. numbered re-dress kits, wristbands with barcodes and tear-off tabs, adhesive labels, etc.). If supplies of tags and labels are insufficient, mark bags with identifying information (name, date of birth, driver s license number, etc.) using a permanent marker. Property bags should be sealed with tape when possible, and the seal initialed by the emergency worker. A Property Receipt form (see RCCC Standard Operating Guideline) will be completed for each individual, identifying the owner, describing the property collected, and establishing a chain-of-custody. If available, a copy of the completed form should be provided to the property owner after they have been successfully decontaminated. Collect multiple bags into cardboard boxes, labeled with the facility name and date (ex Lincolnton High School RCCC, 8/31/2013 ). When full, boxes should be taped shut, marked as contaminated, and the seal initialed by the emergency worker. 7 Cold water tends to close pores, trapping contamination. Hot water tends to open pores, allowing contamination to enter. 17

22 Boxes containing contaminated property could be a source of additional radiation exposure and increased background radiation. They should be moved to a holding area as they accumulate to be secured until removal Collect and secure all potentially contaminated solid waste (i.e. towels, washcloths, soap bars, etc.). When possible, waste should be doublebagged and marked as a radiation hazard EVENT DOCUMENTATION 12.1 All documentation should be maintained on the standard forms provided by the County Emergency Management Office. They will be maintained in a manner prescribed by the instructions on the form Original documentation generated at an emergency facility (logs, contamination records, etc.) should be maintained at the emergency facility until requested by the County Emergency Operation Center In the event original documentation becomes contaminated, it should be either reproduced by photograph, or double-bagged and photocopied. 18

Squeezing the generator lever generates the voltage necessary to charge a dosimeter. A discharge button allows the operator to set a dosimeter exactly on zero. Step 1. Hold the charger upright as shown in Figure Lift the clamp and pull it back to its maximum length. 3. Place the dosimeter in the clamp and fit the dosimeter recess (opposite end from the lens) over the charging contact. This allows for electric contact, connection between the dosimeter and the charger. 4. Squeeze the clamp trigger. Push the clamp forward until the end is against the eyepiece of the dosimeter. 5. Release the trigger. Check that the position of the dosimeter provides a good view through the lens. 6. With the dosimeter locked in place and the lens facing you, point towards a suitable light source (see Figure 2). 7. Look through the lens and observe the dosimeter scale (see Figure 3). 8. Squeeze the generator lever and release lightly a few times. Watch for movement of the hairline fiber from the right of the scale towards zero (0). NOTE: If the dosimeter is not responding, it may be necessary to apply more pressure to the clamp to make a better contact. DO NOT push too hard, dosimeter could be damaged. 9. Squeeze the generator lever again if needed to complete zeroing the dosimeter. 10. If the fiber traveled to the left of the zero, but is still visible, push the discharge button and watch the fiber move to the right until on zero. NOTE: If the fiber traveled to the left of the zero, but is NOT visible, reposition dosimeter and repeat process starting at Step To remove the dosimeter, pull clamp trigger, lift dosimeter to just above end clamp and pull dosimeter straight back to disengage it from the charging contact. 12. View scale to make sure fiber has stayed on zero and has not drifted. 13. Zero all dosimeters, and record their serial numbers and when they were zeroed. 14. On completion, return charger to a normal set-up or configuration for the next use. 29

37 ATTACHMENT 8 WHOLE BODY CONTAMINATION SURVEY GUIDE Whole Body Contamination Survey 1. Have the person stand on a clean monitoring pad. 2. Instruct the person to stand straight, feet apart, arms extended with the palms up and fingers straight out. 3. Using the Ludlum Model 26 contamination survey meter or equivalent, monitor the hands and forearms to the elbows with the palms up, then repeat with the hands and arms turned over. 4. Start at the top of the head, cover the entire front of the body. Carefully monitor areas like the forehead, nose, mouth, neck line, torso, knees and ankles. 5. Have the person turn around and repeat the survey on the back of the body, paying close attention to creases, folds, etc. 6. Monitor the sole of each foot as they move off the monitoring pad. Guidelines for Whole Body Survey (Frisk) If the probe touches the person while monitoring, STOP the monitoring and observe the background count. If unchanged from previous measurement continue with the monitoring, if background is elevated change out the probe cover, and then continue. Move the probe slowly, (about one to two inches per second), and without touching the person over the body while listening for an increase in the count (click) rate. Keep the open face of the probe about one (1) inch from the surface being monitored. Take special care at the feet (especially the bottom of shoes), knees, face, hair, and hands. You may instruct the person to put on a pair of gloves to control any possibility of cross contamination. A whole body survey for the average adult should take about 4 5 minutes. 33

BACKGROUND = (HIGHEST CPM 1 MIN + LOWEST CPM 1 MIN ) 2 Example: (60 CPM highest + 40 CPM lowest ) 2 = 50 CPM Background REASONS FOR TAKING BACKGROUND READINGS 1. Used to compare elevated readings to normal background while performing equipment or personnel monitoring. If this occurs allow probe to rest on potentially contaminated area for seconds to allow response of instrument. 2. If you touch a contaminated person or piece of equipment while surveying, STOP and compare the recorded background reading with what the meter is reading. If elevated, change out the saran wrap, bag, cling wrap or Press n Seal. If not, continue to monitor. 3. Used for indication of a radioactive release from the nuclear plant in the area of the facility. The meter reading would be very erratic. 4. Used to ensure radioactive waste is not causing elevated radiation readings in area. Background Counts per Minute (CPM) would creep upward indicating waste change out is needed. 5. Radiological medical treatments with monitored individuals causing elevated readings. 37

42 ATTACHMENT 11 HANDHELD SURVEY METER SETUP FOR OPERATION HANDHELD CONTAMINATION SURVEY METER OPERATION Setup Checklist for the Ludlum Model 26 Handheld Contamination Survey Meter The Ludlum Model 26 is equipped with an integrated pancake-style Geiger-Mueller contamination detector and is powered by (2) AA batteries. It measures alpha, beta, gamma, and x-ray radiation and is used for detecting surface contamination, screening for environmental contamination, and detecting noble gases and other low energy radionuclides. It should be calibrated annually by a qualified operator using a certified calibration source or electronically using a pulse generator. STEP- (COMPLETE ALL STEPS PRIOR TO USE) WARNING: DO NOT press the red button. This button is used to set specific features of the meter Check for calibration label on the instrument. Do not use if the due date has been exceeded or if a calibration label is not found. Verify meter is in working condition. If battery installation is needed, turn the probe over and open the battery lid by turning the wrist connector eyelet counter-clockwise with a ¼ turn. Load the 2 AA batteries with the + sign end towards the probe. Replace the battery cover and fasten by pushing in and twisting the eyelet clockwise ¼ turn. Turn the instrument ON by pressing the GREEN OK button for about a second and then releasing. The instrument will activate all the LCD segments and audio feature for testing and then display readings in cpm. Allow a 30 second warm up/internal electronic check of meter. 4. Ensure the low-battery indicator is not present. If shown on readout go to step Remove the clear heavy plastic probe cover. 6. Using the small button source located on the attached ID card, place the open probe window directly over the check source. CAUTION: The meter has a digital readout. From 0 to 999 cpm the readout is what you see on the display screen; starting at 1000 cpm the meter switches to kcpm readout. BE AWARE WHEN THE K IS IN FRONT OF THE CPM. When this occurs move the decimal point three numbers to the right. For example; the readout indicates, 1.345kcpm ; this is actually 1345 cpm ; kcpm = cpm The CPM shown on the display should increase. More frequent clicking should be heard with the AUDIO FEATURE enabled. Allow the number to settle out for ~ 1 minute. The CPM displayed must fall within the RANGE that is printed on a label located on the probe side of the instrument and/or on the top of the storage box. Do not use if the instrument s readings remain outside (above or below) the labeled RANGE. Determine Normal Background radiation levels (in CPM) for the assigned work area by observing the average CPM display after 30 seconds. Record on a Background Placard Wrap the entire meter with one layer of Press n Seal, Cling Wrap or Saran Wrap. Smooth out the areas around the probe and digital readout screen. The wrap will cling to itself and provide contamination control for the entire meter. When meter is not in use, turn the meter off by pressing the GREEN OK button for about 5 seconds (a countdown timer will show the meter responding) Calibration is not current. Physical damage to the instrument. Low-battery indicator is present The display is flashing after you turn the instrument to ON. Maximum relative humidity is greater than 95% DO NOT USE meter if the following occur: Meter does not pass the source response check. Meter flashes a ZERO reading. The meter flashes the maximum count rate of cpm and you verify you are not in a radiation field that would cause this reading. 38
