Radiological Air Sampling for the Canadian Forces
Abstract
DREO has performed a study of air sampling methodologies and methods of data analysis following air sampling. This has been done in support of 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 how the CF should perform air sampling. 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 cautions on their use. 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, even when the field-optimised methods of this study are employed. Reliance on these techniques in such scenarios risks high-level radiation exposures.
