On the correction for electronic losses in the γ-spectrometry of short-lived radionuclides

Abstract

In the measurement of short-lived radionuclides, it is necessary to correct for both /residual/ dead time losses and pileup. Although these corrections are interconnected, it appears possible to apply them separately with a final systematic bias of ≦0.2%. The corrections rely on three experimental data: The recorded count rate of an electronic pulser, the total dead time at the beginning of the measurement, an average decay constant for the whole γ-ray spectrum over the measuring period.
