Optimal energy windows of gamma-ray scintillation spectrometer
Abstract
Gamma-spectrometry is increasingly used in the sampling of uranium-thorium ores. It is based on measurements of pulse count rate in the optimal for uranium and thorium areas of the gamma-radiation spectrum. One of the main conditions ensuring high accuracy of sampling is the correct choice of gamma-spectrometer energy windows. This question arises most acutely at creation of spectrometric equipment with small size of scintillators in connection with low speed of counting of pulses in narrow energy windows, recommended usually in the literature.
