State primary standard for flux units, electron flux density and transport density (fluence), energy flux, flux density and transport density (fluence) of electron and bremsstrahlung radiation energy

The results are given of studies of the creation and investigation of a new State standard of the units of electron flux, electron flux density and transport density (fluence), energy flux, flux density and transport density (fluence) of electron and bremsstrahlung radiation energy with energies of up to 50 MeV The characteristics of similar foreign standards are given together with the results of comparisons in the system of laboratories of secondary dosimetry standards (SSDL).
