11. Occupational Dose Limits for Radiation Workers Source of Radiation Whole Body Dose is not to exceed 5 rem/ yr Internal dose is added to WBD

12. Occupational Exposure Limit to the Extremities The Dose Limit to the Extremities may not exceed 50 rem / yr

13. Occupational Dose to the Lens of the Eye Dose must not exceed 15 rem/ yr

14. Radiation Dose in Perspective Health effects are seen only when dose exceeds 25 rem and at a high dose rateHealth effects are seen only when dose exceeds 25 rem and at a high dose rate Occupational radiation doses are monitored and limited by law to 5 remOccupational radiation doses are monitored and limited by law to 5 rem Based on the LNT model, a worker exposed to 1,000 millirem (one rem) per year for 30 years would lose about 30 days of life expectancy due to increased risk of cancer.Based on the LNT model, a worker exposed to 1,000 millirem (one rem) per year for 30 years would lose about 30 days of life expectancy due to increased risk of cancer. Observed Radiation Doses at UGA for Radiation Workers average 0.030 Rem. For 95% of the Radiation Users at UGA, doses are too low to measureObserved Radiation Doses at UGA for Radiation Workers average 0.030 Rem.

17. Safety Concerns about Working in a Radiation Materials Laboratory

18. When entering a radioactive material laboratory always assume there is a potential of radioactive contamination or radiation (dose fields) When entering a radioactive material laboratory always assume there is a potential of radioactive contamination or radiation (dose fields) All Radioactive Materials laboratory are monitored for contamination and radiation. There are limits each laboratory must meet to be able to operate safely All Radioactive Materials laboratory are monitored for contamination and radiation. There are limits each laboratory must meet to be able to operate safely The Advanced Radiation Worker (ARW) is trained to monitor and clean up radioactive materials. The Advanced Radiation Worker (ARW) is trained to monitor and clean up radioactive materials. The UGA Radiation Safety Office will respond to any concerns you have about doing work in a radioactive materials laboratory The UGA Radiation Safety Office will respond to any concerns you have about doing work in a radioactive materials laboratory

19. Always ask the Authorized User (AU) or the lab’s Advanced Radiation Worker (ARW) about radioactive materials use, storage and waste areas before any work is performed.

20. Radiation The natural decay of radioisotopes. This decay consists of energy being released in the form of alpha particles, beta particles and gamma rays Contamination Radioactive material where we don’t want it, i.e., your clothes, shoes, tools, Inside and outside our bodies. We must guard against inhalation, ingestion and absorption. PRIMARY HAZARDS

22. LABORATORY RAM USE AND STORAGE AREAS

29. IF YOU MUST WORK IN ONE OF THESE AREAS BE PREPARED TO DON PERSONAL PROTECTIVE EQUIPMENT (PPE); GLOVES, SAFETY GLASSES, SHOE COVERS OR SLEEVE PROTECTORS IF NEEDED. AFTER THE WORK IS FINISHED, ALL USED PPE SHALL BE PLACED INTO THE LAB’S RAD DRY WASTE DRUM IF CONTAMINATED.

30. Recommended Survey Instrument Ludlum model 3 instrument (Part No. 48-1605) with a 202-608 meter dial and extra cable

31. ASK THE ARW TO DO A PRE WORK SURVEY OF THE WORK AREA AND TO MONITOR YOUR GLOVES AND ITEMS REMOVED IN THE REPAIR PROCESS. ASK THE ARW TO DO A PRE WORK SURVEY OF THE WORK AREA AND TO MONITOR YOUR GLOVES AND ITEMS REMOVED IN THE REPAIR PROCESS.

32. Glove Protocols Know how to remove your gloves without touching your skin or clothing!

33. CAPTURE AND PLACE ANY STANDING WATER INTO THE LABS LIQUID RAD WASTE CONTAINERS; (DRAIN WORK)

34. A drip pan or some type of “Secondary Containment” should be used when working on wet systems

35. ANY SOLID DEBRIS INCLUDING BROKEN PARTS SHALL BE BAGGED AND PLACED INTO THE LAB’S RAD DRY WASTE DRUM. ANY ITEMS REMOVED FROM A CONTAMINATED SYSTEM, PART(S) FROM CONTAMINATED EQUIPMENT OR INSTRUMENTATION MUST BE SURVEYED BY THE LAB’S ARW. ALL SHOULD BE BAGGED AND TAGGED AS WELL BEFORE PLACING IN THE DAW DRUM.

36. CONTAMINATED TOOLS ALL TOOLS USED IN A JOB ON ANY CONTAMINATED SYSTEM OR EQUIPMENT, INSIDE A RADIOACTIVE MATERIALS LAB MUST BE SURVEYED FOR CONTAMINATION. THE LAB’S ARW WILL ASSIST IN PERFORMING THIS TASK. ONCE A CONTAMINATED TOOL IS DETECTED IT MUST BE WASHED AND SURVEYED AGAIN. IF THE CONTAMINATION CANNOT BE REMOVED, THEN CALL THE RADIATION SAFETY OFFICE FOR ASSISTANCE.

37. Hand and foot Survey when exiting the rad work area WHEN WORK IS FINISHED OR YOU ARE TAKING A BREAK, YOU MUST WASH YOUR HANDS AND SURVEY OUT OF THE LAB. THE LAB’S ARW WILL ASSIST YOU IN DOING THIS
