Patent ID: 7038220

Claim:
A radiation dose reading method for a glass dosimeter, in which a fluorescence glass element irradiated with radiation is excited by ultraviolet rays to read a radiation dose by a fluorescence intensity generated from a fluorescence detection surface of the fluorescence glass element, the dose distribution reading method for the glass dosimeter, comprising: using a two-dimensional camera as a detection unit which detects the fluorescence intensity from the fluorescence glass element; a fluorescence intensity measurement step of changing an incident position of the ultraviolet rays in a thickness direction of the fluorescence glass element to apply ultraviolet rays shaped like a thin layer from a side surface other than the fluorescence detection surface of the fluorescence glass element, and measuring the fluorescence intensity in each irradiation position for each pixel division using the two-dimensional camera; and a three-dimensional data output step of synthesizing a plurality of data measured by changing the incident position of the ultraviolet rays to output a three-dimensional dose and a three-dimensional dose distribution of the fluorescence glass element.
