Abstract: The invention relates to a dosimeter comprising a quantity of dosimetric material, the dosimeter being suitable for being irradiated and undergoing a dose measurement by EPR spectroscopy, the enclosure being made from a material not having a response in EPR spectroscopy or having a response different from the response of the dosimetric material after identical irradiation such that the signal of the material of the enclosure decreases as a function of time after irradiation of said material such that a period of time exists after irradiation at the end of which the material has no measurable signal, or a residual signal whose intensity is less than 5% of that measured after irradiation, and the dosimetric material has a constant EPR signal alter irradiation. The invention also relates to a method for measuring the dose absorbed by the dosimetric material contained in such a dosimeter.

Abstract: The invention relates to a radiation-induced radical species characterized in that it has, when measuring a biological nail, hair, or stratum corneum tissue sample by continuous wave EPR spectroscopy at ambient temperature: a Lande factor of 2.004; during Q band measurements at ambient temperature, a minimum signal intensity and a maximum signal intensity, said intensities being reached for magnetic field values separated by 1.8 mT; during X band measurements, a signal forming a singlet; and at the highest frequency, a signal having Lande factor anisotropy. The invention also relates to methods suitable for the identified radical species and intended for preparing a sample, analyzing the measured signal, and estimating a received dose.
