1. Radiation Safety Training Annual Refresher Training Washington State University Radiation Safety Office

2. Why have refresher training? The annual refresher training is designed to reinforce important safety information, provide any new information and to cover areas that have presented problems in laboratories over the past year.

3. In each laboratory that is authorized for radioactive materials use, you will find this form (RHF-3) posted. This form gives the contact information for the Washington state Department of Health. It also list some of your and some of the employer's responsibilities.

4. Good Laboratory Practices Remember Time, Distance, Shielding Wear Protective Clothing: gloves, lab coat, long pants, full toed shoes Designate areas for RAM work Cover work areas with absorbent paper, absorbent side up Use a hood if possible Avoid skin contact with contaminated gloves Survey: your gloves, hands, coat, shoes, and your work area Always wash your hands (even when wearing gloves) after the experiment, as well as before leaving the work area, picking up the phone, etc.

5. CONTROLLING EXTERNAL HAZARD TIME: Radiation dose is proportional to the duration of the exposure. DISTANCE: Radiation dose is proportional to 1/(Distance) 2. SHIELDING: Radiation dose is determined by the type and thickness of shielding materials used. Correct selection of Shielding Materials are a function of type and energy of radiation.

6. Protective Clothing Can be a very effective means of preventing skin, eyes, & clothing from becoming contaminated Always wear Gloves (may want double layer) Always wear your Lab Coat Eyewear to prevent splashes and provide shielding for high energy beta emitters Closed toe footwear and long pants are required It is much easier to remove contaminated clothing than to decontaminate your skin!

7. Contamination Control The major hazard for most radioactive materials on the WSU campus comes from internalizing the radioactive material. Once the radioactive materials are inside your body, you lose all the protections from TIME, DISTANCE AND SHIELDING. Contamination Control is the key to preventing internalization of radioactive materials.

8. Contamination Control Watch out where you put your “hot” hands during an experiment Monitor yourself and your work area frequently for radioactivity (gloves, hands, feet, etc.) Use most sensitive scale on meter (X0.1 or X1) and have the sound on Have meter out and handy Make sure to wash your hands frequently and after finishing an experiment Don’t bring radioactive material to lunch or to your home! Monitor your work area before and after an experiment

9. Surveys After each use of radioactive material : Except H-3, the area shall be surveyed using an appropriate survey meter (not required to be documented) Including the use of H-3, all areas of experimental use shall be wipe tested to determine if contamination is present (not required to be documented) Documented surveys (meter and wipe test) must be completed on either a weekly or monthly basis depending upon the isotope and frequency of use.

10. Survey meter use. Use of Survey Meter review. Check for Calibration Sticker Check battery Check background radiation Check meter response to a known radiation source. Record the check source results and background readings in the meter notebook.

11. Radiation Safety Instrumentation. Before an instrument is used for a radiation safety survey. It must be determined that the instrument is functioning properly and that it is calibrated. This includes both radiation survey meters and LSCs. By using the quality assurance notebooks associated with the instrument. You can determine if the instrument is functioning properly and calibrated.

12. Survey meter Quality Assurance Notebook. Be sure the cover page of your note book is filled in properly. Every survey meter should have a “Survey Meter Quality Assurance Notebook”. Fill in meter manufacturer and serial number. Ludlum 3 111111111 44-9 22222222 Fill in probe model number and serial number. Fill in Meter storage location. Fulmer 123 Fill in Authorized User or Equipment Coordinator’s name and contact phone number and the same for an alternate contact. Arthur Dent 555-4242 Ford Prefect 555-5883

13. Survey meter Quality Assurance Notebook. This is the Response Check Source page in the notebook. Place the meter probe over the check source to get the check source reading. Record this reading on the next page of the notebook.

14. Survey meter Quality Assurance Notebook. Be sure the information has been filled in on this page. Meter and serial number. Probe and serial number. Ludlum 3 1111111111 44-9 222222222 The Expected response to check source, should have been filled in by the Radiation Safety Office. 450 Record the date and your name. 1/1/11 Dr. Who Verify the calibration status of the meter. Record the background reading and the response check reading. 50 450 The meter is now ready to be used for the radiation safety survey.

15. LSC Quality Assurance notebook. Each LSC will have a Quality Assurance Notebook. Be sure to fill in the cover of the notebook. Supervisory Authorized user or equipment coordinator. Plus an alternate and their contact information.

16. LSC Quality Assurance notebook. Be sure the information at the top of the page is filled in. P/E 2910 123456 Fill in the date and your name. 1/1/11 Dr. Who Check the calibration status of the LSC. This information is in the back of the notebook. The LSC must have been calibrated within the past 12 months. Check to see when the last SNC or IPA was run. This is a self check of the LSC. It is done by counting the unquenched standards that came with the LSC. The printout should be in the back of the notebook. It must have been done within the past 7 days. 12/27/10 Enter the number of the program you are using to count your swipes. 14 You are now ready to start counting your swipes. This is the data page inside the notebook.

18. WAC 246-221-150 Security and control of radioactive material and radiation machines. Licensed radioactive materials and registered radiation machines shall be secured from, or controlled in such a manner so as to prevent, unauthorized access or removal from the place of storage. Licensed radioactive materials in an unrestricted area and not in storage shall be tended under the constant surveillance and immediate control of the licensee. The authorized user must Maintain security of radioactive materials or radiation machines under his or her control or possession.

19. Security and control Radioactive materials must be secured. Either by locking the lab door when the lab is unattended or by placing the radioactive materials in a lock box or in a locking freezer or refrigerator. DO NOT LEAVE RADIOACTIVE MATERIALS UNATTENDED.

20. Radioactive materials inventory control. WAC 246-220-020 Records. (1) Each licensee or registrant shall maintain records relating to the receipt, use, storage, transfer, or disposal of radiation sources, In other words, you must maintain an accurate and up to date inventory of your radioactive materials.
