PCT No. PCT/DE96/01405 Sec. 371 Date Jan. 29, 1998 Sec. 102(e) Date Jan. 29, 1998 PCT Filed Jul. 25, 1996 PCT Pub. No. WO97/05506 PCT Pub. Date Feb. 13, 1997The invention pertains to a measurement device comprising two sensors for measuring radiation doses. The sensors are, for example, optical waveguides aligned along a straight line. One of the optical waveguides covers a longer section along the line than the other waveguide; in particular, the difference is at least 20 mm. Measurement using the measurement device is done as follows: the radiation dose along the line of radiation down to the expected penetration depth is measured using the wider sensor; the narrower sensor is used to determine the radiation dose in a volume element within the radiation path. A quotient is formed from the two measurements and used to calculate the radiation depth on the basis of reference values. The proposed device facilitates rapid and simple determination of a penetration depth of an ionizing radiation, for example in tissue.
