State Primary Standard of Units of Equivalent Dose, Power of Equivalent Dose of X-ray and Gamma Radiation
Reproduction and maintenance of the units of equivalent dose, the power of equivalent dose of X-ray and gamma radiations. Dissemination of the units of equivalent dose, the power of equivalent dose of X-ray and gamma radiations to the working standards and workinginstruments of the measuring technology by means of the method of direct measurement in accordance with DSTU 4088-2001 “Metrology. National verification scheme for measuring instruments of equivalent dose, the power of equivalent dose of X-ray and gamma radiations”.
