Live-Timed Anti-Coincidence Counting with Extending Dead-Time Circuitry

Abstract

Anti-coincidence counting is examined as an alternative to conventional coincidence methods for radioactive source strength measurement. Live-timing principles are combined with the use, for all channels, of a shared dead-time of the extending type. Accuracy, precision, decay and background effects are treated and results of comparisons with coincidence measurements given which show agreement consistent with statistical uncertainties of about 0.03%.
