A radiation deep dose measuring apparatus. A corpuscular beam detector of scintillation fibers bundled together into a block is adjusted in position to have a width similar to the radiation range of corpuscular beams; a driving apparatus rotates the corpuscular beam detector and an image receiver together around a center corresponding to a radial axis of the beams; the image receiver captures the image of scintillation light emanating from the corpuscular beam detector; an image signal processing apparatus processes the image signal to produce the distribution of radiation doses as a function of depth; and a displaying apparatus displays the result. The radiation deep dose measuring apparatus allows rapid measurement of radiation doses in three-dimensional space.
