The composition of State Primary Standard of the unit of activity of radionuclides, unit of specific activity of radionuclides, and unit of flux of α and β particles and of photons of radionuclide sources GET 6–2016 and its metrological characteristics are presented. Two new standard plants that implement absolute methods of measurement of the specific activity of radionuclides are introduced in GET 6–2016: the method of ratios of triple and majority double coincidences in a liquid scintillator and the 4πγ counting method. Results of international key and auxiliary comparisons that confirm the measurement capabilities of GET 6–2016 are described. Variations of the measurement chain that take into account the capabilities of GET 6–2016 are considered and existing metrological applications of GET 6–2016 that support the required precision of radiometric measurements in atomic energy, science, medicine, radio ecology, defense, and other areas of application are considered.
