Show affiliationsThe result of extensive Monte Carlo calculations and a re-evaluation of the volume of the primary standard has led to an increase in the determination of air kerma at the VNIIM by 9.6 × 10−3. The contributions to this change are summarized in this short note to announce that the VNIIM primary standard changed with effect from 1 November 2007.
