Abstract
A method for producing standardization samples (11, 21) for obtaining the quench curve which describes the relationship between the counting efficiency and the amount of the quench of the sample is described. According to this method the different quench levels of the standardization samples are performed by covering different standardization samples with scintillation photons permeable foils (12, 13, 14, 25) having variable amounts of black dots (22, 23, 24), which absorb of produced scintillation photons.
