Abstract
The well-known criteria for the selection of the optimum counting condition s in a ZnS(Ag) scintillation detector seem to restrict its applicability. T hese do not consider simultaneously operating voltage and electronic thresh old variation to reach the best counting conditions. Therefore, a more gene ral method for the determination of the optimum counting conditions in ZnS( Ag) scintillation detectors is proposed. In this method, a relationship bet ween voltage and electronic threshold is derived for counting efficiency. I n order to test the method, quality control procedures have been carried ou t as well as the determination of gross alpha activity in environmental sam ples. (C) 2000 Elsevier Science Ltd.
