Abstract
A technique for simulating all detection processes in a 4π(β,e,X)–γ coincidence system by means of the Monte Carlo technique is described. This procedure yields a more realistic behaviour of the extrapolation curve as compared to the usual polynomial fit. The present paper describes its application to the standardisation of a typical pure beta emitter, namely 35S, by the efficiency tracing technique, and an EC-gamma radionuclide, namely 133Ba. The calculated extrapolations were compared to experimental values obtained at the IPEN.
