State Primary Standard of Units of Absorbed and Equivalent Doses of Neutron Radiation

Reproduction and maintenance of the units of absorbed and equivalent doses of neutron radiation.

Dissemination of the units of absorbed and equivalent doses of neutron radiation to the working standards and to the 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 4023-2001 “Metrology. National verification scheme for measuring instruments of the units of absorbed and equivalent doses of neutron radiation”.
