It is our recommendation that the ANSI/IEEE as well as the IEC standards define the test conditions using source activity or gamma-ray emission rate (for specific gamma-ray lines) instead of exposure rate or ambient dose equivalent rate values.
In order to measure the annual effective dose equivalent, conversion coefficients associated with the absorbed dose coefficients in the air are used, the amount of 0.7 Gy / Sv to convert modified coefficients of absorbed dose in air changed to effective dose received annually by adults and 0.2 is used as external occupation factor.
