Repeated Gross Counting of Personal Air Samples to Determine the Presence of a Long-Lived Radionuclide in the Presence of Radon-220 Progeny
Personal air sampling is becoming a much more common technique for tracking internal exposure. The advantages of this technique are that detection limits are very small, especially for alpha-emitting radionuclides, and that the fraction of intake expected on the air sample itself is very large compared to that for other bioassay techniques. In addition, the sample is available for analysis immediately after it is obtained. This allows for modification of workplace controls to mitigate further exposure, initiation of a bioassay program, or, if necessary, provision of medical treatment.
