Abstract
The standardization of 125I by photon-photon coincidence counting and the determination of the activity by a linear efficiency extrapolation is described. The variation of the efficiencies is realized by symmetrically changing the distance between the source and two movable photon detectors with thin NaI(Tl) crystals. Experimental results, data evaluation and the accuracy of the method are discussed.
