Method for shortening the statistical measurement times in the domain of radioactivity measurements

摘要

Method for the detection of an exceeding of a predetermined limiting value in a radioactivity measurement. A total duration of measurement for a contamination measuring device is calculated. Several single measurements are performed with the measuring device, with duration of measurement shorter than the total duration of measurement. After each single measurement, a probability is calculated on the basis of the previously measured measurement values. If the calculated probability is smaller than or equal to the limiting value, a signal is generated and the procedure is ended. Otherwise, further single measurements are performed.
