1 RADIOACTIVE MATERIALS SAFETY REFRESHER EXAM DIRECTIONS: Please print this quiz and fill in the information requested. Mark the correct answer to each question. When completed either scan or the quiz to the Radiation Safety Office or you may fax the quiz to To receive credit for the course, the quiz must be on file with the Radiation Safety and a score of 80% or higher must be achieved. Good Luck! Date: Name: (Please print or type) Department: Phone: URI ID # (Please print or type) Principal Investigator: (If applicable) 1. The maximum permissible dose in a single year to hands of a radiation worker is: 75 mrem 15 rem 5 rem 50 rem 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(s) all of the above URI RAM Refresher Test (07/2017) Page - 1

2 3. The maximum permissible dose to whole body of a radiation workers can receive for a year is: 5.0 rem 7.5 rem 0.5 rem 5.0 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 for their co-workers Promote a safe work environment by following the safety and operating procedures All of the above 5. The maximum permissible dose in a single year to general public is: 100 rem 5 mrem 100 mrem 5 rem 6. When working with radioactive material, appropriate PPE should be worn: Always when working with quantities of 1 mci or more when working with certain isotopes when you remember URI RAM Refresher Test (07/2017) Page - 2

3 7. The best shielding material for H-3 is: No additional shielding required Plexiglass 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 d direction of air flow cannot be determined because there is no air flow no special precautions are needed URI RAM Refresher Test (07/2017) Page - 3

4 11. What is not a general radioactive waste type that are collected by the radiation safety office? Liquid waste Solid waste Liquid scintillation vials waste Natural geo-sample waste 12. Principals of radiation protection include: Shielding Time Distance All of the above 13. 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. Users can report safety concerns to the Radiation Safety Office during working hours through telephone extension: URI RAM Refresher Test (07/2017) Page - 4

5 15. Which item is not proper attire when working with radioactive materials? Long Pants Open toe shoes Lab coat Safety glasses 16. While doing lab contamination surveys in the lab you find an area with removable contamination on the floor in front of the fume hood. You immediately decontaminate the area. What must be done after the decontamination is complete? Document the decontamination on the lab survey forms Dispose the paper towels used for the decontamination in the radioactive waste Check your lab coat and shoes for possible contamination All of the above 17. Sealed source leak test interval is: At least every year At least every 6 months At least every 2 years Whenever the radiation safety office wants 18. The hands and feet (extremities) can tolerate a higher dose of radiation than the blood forming organs. TRUE FALSE URI RAM Refresher Test (07/2017) Page - 5

6 19. All of the following are correct handling of your radiation badge EXCEPT: always wear your badge when working with radioactive materials leave badge in the lab next to materials when not in use store away from all radioactive material never take your badge home 20. Equipment that is not recommended to be used to contain a spill include a plastic tray absorbent pads diaper type material towels URI RAM Refresher Test (07/2017) Page - 6
