It covers ion chamber, gamma spectrometry, Geiger-Mueller, EPD, high volume air sampler, calculations, and radioactive-material shipment surveys. Task steps, review questions, performance checklists, and answers address equipment checks, radiation measurements, sampling, and transport preparation.
Allow the rate reading to stabilize for 20 seconds. (paragraph 4)
Recall that alpha radiation travels only centimeters. Therefore, the probe will need to be as close as possible to the source for an accurate reading, approximately 1/8th to 1/16th of an inch away from the surface being monitored.
When monitoring for beta radiation, use extreme care to protect the beta window when the beta window cover is open as sharp objects can rupture the beta window. (paragraph 9)
Sample volume collected is dependant on local conditions. If dust loading is a concern at your base, or sampling following a radiation dispersal device, 100ft3 should be collected, if not, 1000ft3 is the recommended sample volume. (paragraph 5)
Continuing to wear appropriate PPE and perform a 300-cm2 swipe of the exterior surface of the package and compare results to regulatory limits? (paragraph 9)
