Description
Comparison of accuracy of the methods of total counting, total counting in optimum zones of spectrum and maximum likelihood with reference to a problem of an estimation of activity of isotopes cesium 137, cesium 134 and radon 222 from their gamma-radiation spectra with small statistics in spectrum channels and with a known background is spent. It is shown, that the application for the spectra analysis of the maximum likelihood method gives a gain 10-20% in accuracy in comparison with the methods of total counting and total counting in optimum zones of spectrum (authors). 2 refs., 2 tabs., 3 figs
