a circuit for recharging the electrical accumulator;

wherein the dosimeter comprises;

a first radiation sensor for detecting sinusoidal X-radiation and γ

(gamma) radiation;

a filter for the first radiation sensor, which is transparent to γ

(gamma) radiation but sensitive to X-radiation, the filter adapted to correct overstated values received in an X range to a value within admissible margins of error;

a first amplification stage for amplifying a signal from the first radiation sensor to produce an amplified signal;

a circuit for processing the amplified signal of the first radiation sensor, and converting said amplified signal into one of;

a dose value and

a value that can be interpreted as a dose;

a memory module in which information on the dose received in a fixed period is stored;

a communications module;

a second radiation sensor for square-wave X-radiation, with a corresponding second amplification stage, said second radiation sensor being identical to the first radiation sensor, and said second amplification stage being separate from the first amplification stage for the first sensor; and

a dosimeter control device with at least one base for recharging the dosimeter, said base provided with;

a recharging circuit; and

a system for communication with the dosimeter.

2. A dosimetric monitoring device, according to claim 1, wherein at least one of the first and second radiation sensors include a PIN type diode.

3. A dosimetric monitoring device, according to claim 1, wherein the second amplification stage for square-wave X-radiation is connected to the first X-radiation sensor, said second amplification stage being different from the first amplification stage.
