SUPPLEMENTARY COMPARISON

The Russian (VNIIM) and French (BNM-LNHB) national primary laboratories organized in 1997 a bilateral comparison in beta dosimetry. This comparison of national standards, EUROMET.RI(I)-S2.B2, was carried out through a transfer ionization chamber manufactured by the VNIIM. The calibration factors of this chamber were determined by both laboratories in terms of absorbed dose rate at 7 mg cm-2 of tissue depth, for the beta radiation fields of 90Sr–90Y, 204Tl and 147Pm.
