Abstract
A method for the evaluation of sample activities in multidetector liquid scintillation counters. All prepared quench curve standards are measured only in one reference detector in order to establish the relationship between the quench levels and the counting efficiencies. In addition, only two of the standards, preferably those with lowest and highest level of quench, are measured in every detector in order to establish the relationship of the quench levels between the reference detector and any other detector and in order to establish the relationship of the counting efficiencies between the reference detector and any other detector. The activities of unknown samples are evaluated by utilizing the predetermined relationships.
