State Standards

The current state of the national primary standard GET 8-2011 for the units of air kerma, exposure, their rates, and energy flux (power) in x- and gamma-radiation, which was revised in 2007–2011, is examined. The structure of the standard, and its operating principles and metrological characteristics, are described.
