2011 Radiation User Refresher
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.

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, [email protected] or 9-3911• EH&S Director Brent Cooley [email protected] or 9-2553• Chair, Radiation Safety Committee George Brown,
[email protected] or 9-2327• EH&S e-mail [email protected]• Web Form http://ehs.ucsc.edu/I2P2/pubs/hazalert.html

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.

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

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.

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.

Required Actions on Identification of Issue

2011 Radiation User Refresher
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?

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.

2011 Radiation User Refresher
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.

(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

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.
