1. 1 Radiation Safety Awareness Training Radioactive Packages Centre for Environmental Health & Safety Management

2. 2 Radiation Safety Awareness Training – Radioactive Packages TRAINING OBJECTIVES Procedures to deal with incorrect deliveries of packages with radioactive materials Appendix 1 – policy Review other parts of workbook as we go along in today’s session Appendix 1 – policy Review other parts of workbook as we go along in today’s session

3. 3 Radiation Safety Awareness Training – Radioactive Packages WHAT IS RADIATION? What is Radiation? Health effects Types of shipments of radioactive materials to Ryerson Procedures for dealing with Packages containing Radioactive Materials at Ryerson

4. 4 Radiation Safety Awareness Training – Radioactive Packages WHAT IS RADIATION? Radiation is Energy from an Atom

5. 5 Radiation Safety Awareness Training – Radioactive Packages RADIOACTIVITY Atoms try to become stable by releasing energy from the nucleus This “atomic” energy is called RADIATION

6. 6 Radiation Safety Awareness Training – Radioactive Packages RADIOACTIVE DECAY Radioactive energy is released until the atom is stable and becomes not radioactive Process called radioactive decay Some radioactive materials may decay for only a few seconds … some may take days or years to become non radioactive

7. 7 Radiation Safety Awareness Training – Radioactive Packages Where Do You Find Radiation? Nature Radiation is all around us, and has been present since the birth of this planet. artificially made by humans

8. 8 Radiation Safety Awareness Training – Radioactive Packages Where Do You Find Radiation? We are all exposed to radiation every day, all the time. It comes from: The foods we eat The earth and sun Building materials Radon Medical uses of radiation Consumer products – e.g. smoke detectors

9. 9 Radiation Safety Awareness Training – Radioactive Packages HEALTH EFFECTS How will all this affect me? How much will I be exposed???

10. 10 Radiation Safety Awareness Training – Radioactive Packages HEALTH EFFECTS Radiation is one of the best-investigated hazardous agents

11. 11 Radiation Safety Awareness Training – Radioactive Packages HEALTH EFFECTS

12. 12 Radiation Safety Awareness Training – Radioactive Packages HEALTH EFFECTS If penetrates tissue, may be absorbed by cells if enough absorbed, then cells may not be able to repair themselves and can be changed or damaged. can cause genetic damage or disease these effects are most likely when person exposed to high levels

13. 13 no observable effects for levels 50 times above background

14. 14 Large Doses (NOT AT RYERSON) At doses > 2500 times above background, skin begins to show “sunburn Eye damage (cataracts) can results at doses > 3000 times above background

15. 15 does not cause any unique forms of cancer that are not normally observed in humans Evaluation of risk: From small doses, risk is so low that it cannot be separately and distinguished from natural causes estimates the risk of developing cancer to be 0.8% greater for one time exposure 50 times above background levels in Toronto low risk
