DREO has performed a study of air sampling methodologies and subsequent methods of data analysis. This has been done in support of Defence Services Procurement Project 00002199 (Radiation Detection, Identification, and Dosimetry) and is focussed on what methods would be best suited to the Canadian Forces. As part of this work, DREO performed a number of experimental trials to demonstrate and test the principles and methods of air sampling. A suggested method is presented for CF air sampling procedures. It uses high-volume air samplers, alpha-beta probes for detection of contaminants on the filter, and gamma-ray spectroscopy for additional sensitivity in some cases. Data analysis approaches are suggested, with appropriate caveats. One of the major findings of this study is that radon and thoron backgrounds present a serious impediment to the detection of low levels of airborne contaminants. In fact, the equipment discussed in this work is insufficient for the detection of alpha-emitting contaminants down to safe levels, even when the field-optimized methods of this study are employed. Reliance on these techniques in such scenarios risks radiation exposures.
