State Primary Standard of Units of Exposure Dose, Power of Exposure Dose of X-ray and Gamma Radiation
Reproduction and maintenance of the units of exposition dose, power of exposition dose of X-ray and gamma radiations.
Dissemination of the units of exposition dose, power of exposition dose of X-ray and gamma radiations to the secondary standards, working standards and working instruments of the measuring technology by means of the method of direct measurements and comparisons with a help of comparator in accordance with DSTU 4089-2001 “Metrology. National verification scheme for measuring instruments of exposition dose, power of exposition dose of X-ray and gamma radiations”.
