ABSTRACT:
In a depth dose measuring apparatus, a fluorescent substance block (1) bundling scintillation fibers of which radiation absorption characteristic is close to that of tissue, is disposed orthogonally to the incident direction of radiation (4-1). The fluorescence intensity distribution on the fiber end faces of the fluorescent substance block (1) is measured by an image measuring device (6). Therefore, the two-dimensional fluorescence intensity distribution in the incident direction of radiation and in another orthogonal direction, that is, the absorption dose distribution can be measured simultaneously by one irradiation. Moreover, if the fluorescent substance block (1) is composed by laminating plate-form scintillators, one-dimensional absorption dose distribution in the depth direction can be measured by one operation.
