Reproduction and maintenance of the units of absorbed dose, power of absorbed dose of X-ray gamma radiations. Dissemination of the unit of absorbed dose, power of absorbed dose of X-ray gamma radiations to the 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 4087-2001 “Metrology. National verification scheme for measuring instruments of the unit of absorbed dose, power of absorbed dose of X-ray gamma radiations”.
