1)Â Â Â Â Â Personal Checks: After each use of radioisotopes, before exiting the Rad Van, check your hands, work area, bottom of your shoes, and the front of your coat and sleeves with a Geiger counter.
2)Â Â Â Â Â Bi-weekly wipe test: The wipe test should be conducted every 2 weeks at designated locations. Please see attached rad Van layout and log sheet. The samples will be analyzed with the liquid scintillation counter. If a contaminated area is detected, further detailed wipe test should be conducted to pinpoint the contaminated area. If cleanup is required, wipe test is also required after clean up.
3)Â Â Â Â Â Samples and equipment: Any samples or equipment/supplies that need to be removed from the Rad Van, a wipe test will be conducted and proof that it is not contaminated.
4)Â Â Â Â Â Drain Tank test: Liquid in the Rad Tank should be tested weekly or when the tank is full. A sample will be tested with the liquid scintillation counter. If the results are negative of radioactivity, the content in the tank can be drained on deck, with permission from LO/ALO. If the test results shown contamination of radioactive material, the entire content will be transfer to a carboy for storage and disposed as radioactive contaminated waste at end of the expedition.
5)Â Â Â Â Â Isotope check out log sheet: User(s) will fill out the checkout sheet every time the radioactive material is used. See attached usage log sheet
