  3. RADIOACTIVE MATERIALSSIGNS & LABELS

  4. Radiation Postings / Labels • Rule .03 (11) specifies requirements for: • posting or labeling • Rooms • Containers • Machines Standard Radiation Symbol Trefoil

  5. Laboratory Postings Required “Notice to Workers” and Emergency Contact Information should be posted at the entrance to your lab Caution Sign and Hazards Radioactive Materials Posting Lab Emergency Phone Numbers Georgia DNR Notice to Workers RSO Emergency Phone Numbers

  6. Door Sign • Waste Containers (every 180 o) • Radioactive Materials Use Hoods • RAM Use and Storage Areas • Any location that contains RAM

  7. Instruments

  8. RULES & REGULATIONS

  9. Georgia Department of Natural Resources Environmental Protection Division • Key Parts of the “Rules and Regulations for Radioactive Materials, Chapter 391-3-17” • Part .01: General Provisions • Part .03: Standards for Protection Against Radiation • Part .07: Notices, Instructions and Reports to Workers: Inspections.

  10. Occupational Dose Limits for Radiation Workers Source of Radiation Whole Body Dose is not to exceed5 rem/ yrInternal dose is added to WBD

  11. Occupational Exposure Limit to the Extremities The Dose Limit to the Extremities may not exceed50 rem / yr

  12. Occupational Dose to the Lens of the Eye Dose must not exceed15 rem/ yr

  13. Radiation Dose in Perspective • Health 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 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. • 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 measure

  14. A As L Low A As R Reasonably A Achievable A L A R A Philosophy Radiation doses are kept as low as possible Stems from Linear-No-Threshold dose model ALARA program required by Federal and State regulations

  15. Keys to ALARA TIME DISTANCE SHIELDING

  16. Safety Concerns about Working in a Radiation Materials Laboratory

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

  18. 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.

  19. PRIMARY HAZARDS RadiationThe 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.

  20. What to look for in Radioactive Materials Laboratory

  21. LABORATORY RAMUSE AND STORAGE AREAS

  22. 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.

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

  24. 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.

  25. Glove Protocols Know how to remove your gloves without touchingyour skin or clothing!

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

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

  28. 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.

  29. 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.

  30. 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 Hand and foot Survey when exiting the rad work area
