The methods that use scintillation counting with ZnS(Ag) scintillation detector are widely used for gross alpha activity determination. Optimal counting conditions could be provided by properly setting of operating voltage and by this means, the long term stability could be achieved. The common criteria for the selection of optimal counting conditions for a ZnS(Ag) scintillation detector do not consider simultaneously operating voltage and discrimination level variation. In present method a relationship between voltage supply and discrimination level is derived for counting efficiency.
