method of gamma ray spectrometric survey and device for its implementation

摘要

1.method of gamma ray spectrometric survey, including the measurement of gamma quantum in the energy interval, corresponding to the characteristic lines primary radionuclide s and the fact that, in order to improve the accuracy of measurement in the determination of the concentrations of radionuclides in the rocks, at the same time measure u0440u0430u0434u0438u043eu044fu0440u043au043eu0441u0442u043du0443 yu temperature rocks.using it for the correction of measurements of gamma u043au0432u0430u043du0442u043eu0432.2.the device for gamma spectrometric survey containing gamma spectrometer and the different, it is further equipped with u0441u0432u0435u0440u0445u0432u044bu0441u043eu043au043eu0447u0430u0441u0442u043eu0442u043d ies u0440u0430u0434u0438u043eu043cu0435u0442u0440u043eu043c, functional converter and at least one link with adjustable ratio of transmission, which is connected with the first entrance exit ha mma - spectrometer.a second input is connected via a functional converter with u0441u0432u0435u0440u0445u0432u044bu0441u043eu043au043eu0447u0430u0441u0442u043eu0442u043du044bu043c u0440u0430u0434u0438u043eu043cu0435u0442u0440u043eu043c, out link is connected to the transmission with adjustable coefficient the registrar.
