The Radiological Protection Ordinance requires measurement of the personal dose for determination of the body dose. In Germany, the personal dose is the dose equivalent measured in the measuring variables of depth dose and skin dose at a spot representative of radiation exposure at the body surface. The depth personal dose in the case of whole body exposure to penetrating radiation is an estimated value for the effective dose and the organ doses of deep organs and the skin dose an estimated value for the skin dose. (See ‘dose’).
