It covers ion chambers, gamma spectrometers, Geiger-Mueller meters, electronic personal dosimeters, and high-volume air samplers. It also contains training and performance material for investigating suspected ionizing radiation overexposures and performing radiation calculations.
To ensure accurate results, it is very important to take frequent background spectra in the actual monitoring location. (paragraph 4)
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 1)
