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.

Radiation Safety Functions


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

• Document Issue - RS or Lab

• Take Corrective action - lab

• Evaluation of cause - RH (PI)

• Sanctions for serious, willful violations - RSC


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.


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.


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.


Security

• Secure RAM from unauthorized removal.

• Immediately report missing RAM


Wear your Lab Coat


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.


Required Postings

• Sign on Door

• Notice to Employee

• Emergency Numbers

• Work Area Marked


Lab Conditions Frequently Identified by Inspector

• Evidence Food/Drink

• Dosimeter(s) Worn

• Meter Available

• Meter Check-Okay

• Evident RAM Security


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.


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.


Avoid Ingesting Radioactive Material

NO–Eating

–Drinking

–Smoking

–Applying Cosmetics

–Mouth Pipetting


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


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.
