1 RADIOACTIVE MATERIALS SAFETY REFRESHER EXAM 2014 DIRECTIONS: Please print this quiz and fill in the information requested. Mark the correct answer to each question, either scan and the quiz to or send it through campus mail to EHLS, Mail Code You may also fax the completed quiz to To receive credit for the course, the quiz must be on file with EHLS and a score of 80% or higher must be achieved. Good Luck! Date: Name: (Please print or type) Department: Phone: People Soft ID # (Please print or type) Principal Investigator: (If applicable) 1. The maximum permissible dose in a single year to the eyes of a radiation worker is: 75 mrems 15 rems 5 rems 50 rems 2. Radioactive materials can gain entrance into the body by ingestion, absorption through skin and inhalation. The following practices will prevent radioactive material from gaining entrance into the body Do not pipette liquid radiochemical by mouth Use double gloves if you have skin abrasion or open wound Use of approved fume hoods when working with volatile radiochemical RAM Refresher Test (1/14) Page - 1

2 3. The maximum permissible dose that a fetus is allowed to receive for the entire pregnancy is: 5.0 rem 7.5 rem 0.5 rem 0.5 mrem 4. Every person authorized to work with radioactive material at the University is required to Familiarize themselves with the rules and policies Observe the rules for their protection and that of their co-workers Promote safe work environment by following the safety and operating procedures All of the above 5. The maximum permissible dose in a single year to the whole body of a radiation worker is: 5 rems 75 mrems 0.5 rem 5 mrem 6. When working with radioactive material, a lab coat should be worn: Always when working with quantities of 1 mci or more when working with only certain isotopes when you remember 7. The preferred shielding material for P-32 is: Wood Plexiglas RAM Refresher Test (1/14) Page - 2

3 Paper lead 8. In the event that your skin becomes contaminated, the first thing you should do is scrub your skin with stiff brush and harsh soap wash with mild soap and warm water do nothing wait for it to decay before proceeding with your work 9. What is ALARA? As low as reasonably achievable As long as reasonably achievable As long as readily attainable As low as readily available 10. When working with a potentially volatile (vaporizing) compound, the procedure should be carried out in a fume hood with adequate flow rate. To ensure proper protection, direction of air flow should be flowing from hood towards the researcher away from the researcher into the hood Direction of air flow cannot be determined because there is no air flow no special precautions are needed 11. Labeling of radioactive waste as to its content and approximate activity levels is necessary on only liquid waste on only solid waste on all scintillation vials on all radioactive waste RAM Refresher Test (1/14) Page - 3

4 12. Principals of radiation protection include: Shielding Time Distance All of the above 13. Smoking, eating and drinking in the radioactive materials laboratory: is OK as long as you are not handling the radioactive material is never allowed for any reason is OK with special permission is OK under any reason 14. Authorized Users can report safety concerns to the UH Environmental Health and Life Safety (EHLS) Department during working hours through telephone extension: What is the proper attire when working with radioactive materials a. Pants, sandals, lab coat, safety glasses b. Shorts, sandals, lab coat, safety glasses c. Shorts, lab coat, gloves, safety glasses d. Safety glasses, lab coat, closed toe shoes 16. While doing lab contamination surveys in the lab you find an area of removable contamination on the floor in front of the fume hood. You immediately decontaminate the area. What must be done after decontamination is complete? document the decontamination on the lab survey forms RAM Refresher Test (1/14) Page - 4

5 dispose of the paper towels used for the decontamination in the radioactive waste check your lab coat and shoes for possible contamination 17. Radioactive material must be secured when not in use. TRUE FALSE 18. The hands and feet (extremities) can tolerate a higher dose of radiation than the blood forming organs TRUE FALSE 19. All of the following are correct handling of your radiation badge EXCEPT: always wear your badge when working with radioactive materials share your badge with a friend who left theirs at home when not in use store away from all radioactive material never take your badge home 20. Equipment that can be used to contain a spill include a plastic tray absorbent pads diaper type material RAM Refresher Test (1/14) Page - 5
