LOCAL DOSIMETER AND MEDICAL APPARATUS USING IT

摘要

PROBLEM TO BE SOLVED: To obtain a local dosimeter by which a radiation can be measured with high accuracy by removing the influence of a noise, especially Cherenkov light, which is generated when the radiation is incident on an optical transmission part. SOLUTION: A scintillation fiber 1 which emits light due o the incidence of a radiation is provided. An optical transmission fiber 3 which transmits the light from the scintillation fiber 1 is provided. A band-pass filter 2 which removes a noise generated when the radiation is incident on the optical transmission fiber 3 and through which light at a specific frequency is transmitted is provided. A light detection part 4 which detects the light transmitted via the band-pass filter 2 is provided.
