Measurement of the activity per unit mass with hand-held alpha and beta detectors.
This paper describes how to use hand-held alpha and beta detectors to measure volume or mass contamination (Bq g-1) instead of the usual surface activity (Bq cm-2). As a proof of principle, measurements with a hand-held detector of the specific activity of K in potassium chloride yielded the expected result. Field measurements agree well with the results from analytical laboratories.
