АТ1315 Gamma Beta Spectrometer Applications Radionuclide monitoring of water, ▪ Spectrometric and radiometric monitoring foods, raw and other materials of radionuclide content in water, foods, agricultural raw materials, industrial, construction and forestry materials, environmental objects (soil, vegetation, etc.), metallurgical industry produce and products of other industries. Gamma spectrometer Gamma and beta spectrometer Features Two channel scintillation gamma and beta spectrometer is designed for is integrated into smart probes simultaneous and selective detection of the following: ▪ Cs, 134Сs, 131I and 90Sr radionuclide specific activity in natural samples 40 ▪ Specific effective activity of К, Ra, Can be used for rapid radioactive purity determination of standardized sample ▪ Continuous automatic LED stabilisation of spectrometric path in measurement mode heat of metal. ▪ Calibration integrity monitoring by means of integrated radioisotope check sample with less than the minimum significant activity Operation Gamma and beta spectrometer operation principle is based on measurement ▪ Computer spectra processing with maximum likelihood method and transformation of gamma and beta radiation, detected by standalone ▪ Automatic recording of sample density detection units, into amplitude distributions, which are further transformed into digital code and saved in the detection unit memory. ▪ Spectra metering with on-line visualisation ▪ Simultaneous spectra metering and processing ▪ Methodological support of measurements INSTRUMENTS AND TECHNOLOGIES FOR NUCLEAR MEASUREMENTS AND RADIATION MONITORING
