IONIZING RADIATION MEASUREMENTS DETERMINATION OF THE CASCADE SUMMATION COEFFICIENTS OF GAMMA QUANTA FOR A SEMICONDUCTOR DETECTOR IN THE 59-2754 keV RANGE

摘要

A method of measuring the cascade summation coefficients of a semiconductor Ge(Li)-detector with a relative efficiency of 15% without using calculation programs is proposed. An uncertainty of 2% (k = 2) in the cascade summation coefficients obtained for energies of 59-2754 keV is obtained. A method of constructing the overall efficiency curve of the detector up to an energy of 2754 keV using ~(60)Co, ~(88)Y, and ~(24)Na radionuclides is proposed. The measured cascade summation coefficients are compared with those calculated using the ETNA program (LNHB, France).
