As part of its ongoing support to DSP 00002199, the RAD group at DRDC Ottawa was asked to investigate how best to use the low-volume air sampler procured by the project for the Canadian Forces. The RAD group has used this air sampler to take a number of air samples at sites around the DRDC Ottawa campus. These air samples have been analysed via a number of techniques, many of which rely on measurements of the sampler filters by the RDS-100 survey meter system also procured by the project. A scheme for data analysis is suggested, with an emphasis on simplicity and field expediency. The sensitivity of this scheme is evaluated in terms of the minimum detectable activities of a collection of isotopes, and the airborne hazard that these would pose to deployed forces. It is shown that the air sampler is capable of providing warning of airborne hazards consisting of low-mass beta- and gamma-emitting radionuclides. However, for hazards consisting of alpha-emitting transuranic elements, this system is incapable of detecting the hazard at levels corresponding to NATO or civilian action levels.
