METHOD FOR DETERMINATION OF ACTIVITY OF GAMMA-RADIONUCLIDE

摘要

Method for determination of activity of gamma-radionuclide at investigation reactor IR-100 by means of gamma-spectrometers includes use of set of sample spectrometric gamma-emitters (ZSGV). One determines geometry of measurement of rate of count from sources ZSGV and gamma-radio-nuclide being measured. By results of measurement of parameters of ZSGV one plots graphical dependence of effectiveness of measuring installation on energy of gamma-quantums emitted with ZSGV. One determines analytical dependence that describes the curve obtained. Effectiveness of measuring installation is determined by the graph obtained or from analytical expression with account of energy of gamma-quantums emitted by radionuclide being measured.
