ABSTRACT:
The object of the invention is a method for the evaluation of sample activities in multidetector liquid scintillation counters. According to the invention the memory of said apparatus is provided with a theoretically derived model for each isotope between the counting efficiencies and the quench levels. In addition at least one standard is measured in each detector in order to establish relationships between said theoretical model and each detector. The activities of an unknown sample is evaluated by utilizing said theoretical model and said relationship.
