The invention concerns a dosimeter for the determination of an absorbed dose (D) of a radiation field (26), the dosimeter having a dosimeter probe (12), which has (a) a sensor (14), which has a sensor volume that emits electrical charges (Q) when exposed to ionizing radiation, (b) a cable (18) for the transmission of the charges (Q) and (c) an evaluation unit (20), which is designed for the capture of a physical quantity (U), which corresponds to the emitted electrical charge (Q), which is characterized by the fact that the evaluation unit (20) is arranged for (d) the detection of a interval cycle of the radiation field (26), (e) the recording of a measurement number of measurements of a physical quantity (U) corresponding to the electrical charge, which is always read at the same time relative to the interval cycle, so that an initial raw measured value (U1) and at least one second raw measured value (U2) are obtained per interval, and (f) the calculation of a measured value (D) from the at-least two raw measured values (U1, U2) which is unambiguously related to the absorbed dose (D) deposited in the sensor volume. |
