Abstract
Low quenched samples containing 241Am, 137Cs, or 60Co have been investigated by liquid scintillation counting using two-vial configuration, with the aim to study the effect of incidental radiations on the counting efficiency of α or β particles. For β determination, the effect of incidental radiations mainly depends on whether they are in coincidence with the β particles. While for α determination, the counting efficiency of α particles can hardly be affected by the incidental radiations if a proper α/β discrimination parameter is applied. When coincidence exists, summation effect can offset the effect of incidental radiations.
