Metrology System of Ionizing Spectrometry ά-, β-, γ- Radiation

The elements of the system of metrological support for the spectrometry of ionizing ά-,  β-, g- radiation as the basis of analysis and control of the content of radionuclides in environmental objects, foodstuffs, soils, analysis of the purity of radionuclide materials in order to detect contaminants of radionuclides, control in the degree of burnout of telescopes, the determination of the content of natural radioactive substances in ore, the natural and man-made radionuclides in living organisms are presente. The analysis of the legislative, normative, scientific, technical and methodical basis of metrological support for spectrometry of ionizing radiation has been carried out. The main problems of applied spectrometry of ionizing ά-,  β-, g- radiation are considered, and the state of its normative support is analyzed. The necessity of the creation of new normative and methodical documents for the replacement of abolished for the applied use of spectrometry ά-,  β-, g- radiation, systemic measures in the metrological provision of scientific activity in the transition to measurement uncertainty is indicated.
