Radiation Source Refresher Class 2011 UCSC

1. Radiation Source Refresher Class 2011 UCSC Conrad Sherman x9-3911 RSO/Health Physicist Marcus Balanky x2-7158 ARSO/ Health Physicist Vern Ares x9-5167 Assistant Health Physicist Environmental Health & Safety Radiation Safety

2. Annual Refresher Training is Required • Option 1 –Challenge the test • Option 2 – review this presentation, radiation safety manual, rpm fundamentals workbook (ucsc radiation) • Option 3 –request a class then • Pass the Test • Test is on e-commons • Please complete within 30 days of your last test date (if you don’t know it, then look on e-commons, in your PI’s radiation safety folder/training is a report showing training for all users within your lab group. Location of EHS/Radiation published materials http://ehs.ucsc.edu/lab_research_safety/xray_safety.php

3. Radiation Safety Functions

4. You Have the Right to Report Radiation Safety Concerns and Violations • Report concerns or suspected radiation safety violations to your supervisor. If it is not adequately corrected, notify the RSO • RSO Conrad Sherman, csherma1@ucsc.edu or 9-3911 • EH&S Director Brent Cooley bcooley@ucsc.edu or 9-2553 • Chair, Radiation Safety Committee George Brown, gbrown@ucsc.edu or 9-2327 • EH&S e-mail ehs@ucsc.edu • Web Form http://ehs.ucsc.edu/I2P2/pubs/hazalert.html

5. Survey Meter Use • You should know how to use the survey meter. • Remember that you must perform a preoperational check each time you use the meter. • Battery • Background • Calibration • Check source • If you’re uncertain about how to perform the preoperational check or to do a survey, review the process with your lab manager or ask EHS.

6. Dosimeters are required • Are likely to receive >10% of an occupational dose limit. • Enter a high radiation area. • Routinely work with >5 mCi quantities of I-125. • Routinely work with >1 mCi quantities of P-32. • As per your RUA

7. Dosimeters • A whole body dosimeter is worn on the to torso in a location where it is likely to receive the highest exposure. • Ring dosimeters are worn underneath disposable gloves. • Wear ring so chip faces source.

8. Examples of Compliance Issues • Eating/drinking/smoking/storing food in RAM areas. • Inventory and survey records that do not reflect actual radioactive materials on hand and/or in use. • Failure to secure RAM and/or rad waste from unauthorized use or removal. • Improper radioactive waste storage.

9. Required Actions on Identification of Issue • Document Issue - RS or Lab • Take Corrective action - lab • Evaluation of cause - RH (PI) • Sanctions for serious, willful violations - RSC

10. Consistently fill out records • Survey Logs, use log, etc. • Are your records easy to find? • Be sure sources are appropriately labeled. Remove unnecessary labeling. • Is training for all lab personnel up-to-date? • Pay attention to security matters. Is your lab locked when no one is there?

11. RAM shipment • Verify you received the correct RAM, chemical form, and activity. • Wear PPE to open RAM shipment. • Immediately include received material into your lab’s RAM inventory and record activity in units of millicuries. • Assume that the inner surfaces of the package (source vial and packaging material) may be contaminated and handle accordingly until proven otherwise by survey. • Before discarding the packing material from the shipment. Obliterate all radiation warning labels before discarding as normal trash.

12. Practice ALARA • The less TIME spent near RAM, the less dose received. • The more DISTANCE between you and RAM, the less exposure received. Doubling the distance from RAM reduces exposure by ~1/4. Use tongs or other remote-handling tools to reduce exposure to fingers and hands. • For SHIELDING BETA emitters use Plexiglass. • For SHIELDING X- or gamma ray use Lead • one size doesn’t shield all. • Contact the Radiation Safety Office to determine the proper thickness and types of shielding material to use.

13. (s)WIPES and Smears • They are used to determine if removable contamination is present from any type of radioactive material when counted. • Use disc or paper towel for large area if a GM is used to check survey media

14. Remember to Document Your Surveys! • • Surveys must be done at a frequency to ensure that exposure to RAM is kept ALARA (as low as reasonably achievable). • • Keep your survey records in a form that the can audit. • blank survey record forms.

15. User Responsibilities • Keep RAM use authorization current. • Complete radiation safety training. • Maintain up-to-date inventory records. • Perform and document RAM surveys frequently to control contamination and keep exposure ALARA. • Follow required radiation safety and radioactive waste handling and disposal policies.

16. Security • Secure RAM from unauthorized removal. • Immediately report missing RAM

17. Wear your Lab Coat

18. Regulations • Comply with all pertinent regulations of the Campus Radiation Safety Manual. • A copy of the RSM is to be maintained by the RH. • All personnel listed in the permit are required to read and be knowledgeable regarding provisions of the RSM.

19. Required Postings • Sign on Door • Notice to Employee • Emergency Numbers • Work Area Marked

20. Lab Conditions Frequently Identified by Inspector • Evidence Food/Drink • Dosimeter(s) Worn • Meter Available • Meter Check-Okay • Evident RAM Security

21. Surveys and Waste Disposal • A suitable survey instrument must be maintained in the lab. • Periodic wipe tests are to be made per RUA. • Known radioactive waste shall be collected and packaged for waste disposal.

22. Radioactive Material Transfers • Radioactive materials may not be acquired for trans-shipment. • No radioactive materials are to be transferred between authorized users without the prior approval of the Radiation Safety Office.

23. Avoid Ingesting Radioactive Material NO • Eating • Drinking • Smoking • Applying Cosmetics • Mouth Pipetting

24. Documenting Surveys • Contamination surveys must be documented • Record the following: • date performed • area(s) surveyed (a map helps!) • results • identity of surveyor • instrument used • action taken if contamination is found

25. Personal Contamination • Notify the RSO immediately of any case of personal contamination. • Uninjured persons should remove contaminated clothing and wash or use emergency shower or eyewash as needed. Do not delay. • If an injured person is contaminated, do not delay medical attention.
