Patent ID: 7154097

Claim:
A method for measuring a dose of irradiation with a beam of ionizing radiation capable of creating Cherenkov radiation, in which a scintillator ( 1 ) for emitting scintillation light, whose intensity is a function of the dose of this beam irradiating this scintillator ( 1 ), is arranged below this beam, the scintillator ( 1 ) is coupled, via an optical fiber ( 2 ), to a device ( 8 ) for measuring the light emitted by the scintillator ( 1 ), and the quantity of light transmitted by the optical fiber ( 2 ) is measured, wherein the light emerging from the opposite end of the optical fiber ( 2 ) from the one coupled to the scintillator ( 1 ) is filtered using two bandpass filters having cutoff bands in different parts of the spectrum, the intensity of the light coming from these two filters is measured, a plurality of times, and wherein a plurality of quantities of scintillation light and Cherenkov radiation are calculated on the basis of the plurality of measurements in order to deduce a first irradiation dose value therefrom.
