Abstract
A method of calibrating non-discriminating gamma radiation detectors f or environmental level measurements is described. It is based on a met hod used to calibrate field gamma spectrometers, and has several advan tages over the more traditional point-source approach. Radiological me asurements are taken on pads with known concentrations of potassium, u ranium and thorium, and the sensitivities to these naturally occurring terrestrial sources of gamma radiation are determined. Measurements c an then be converted into radionuclide concentration or exposure rates . Copyright (C) 1996 Elsevier Science Ltd
