Abstract

True coincidence summing (TCS) corrections are increasingly being calculated rather than measured. According to the established standards the uncertainty of the calculated TCS correction values has to be estimated. We carried out a systematic study of the uncertainty of the TCS correction factors resulting from uncertainty in the input efficiencies for a large number of radionuclides and we find that the relative uncertainty of the TCS correction factors is in general proportional to the value of the correction factor itself.
