RADIATION MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To eliminate the drawback of a radiation measuring device that disposes radiation detection elements in tandem using a pinhole collimator in which: the simple composition of signals of radiation detection elements disposed in tandem generates a blur caused by the difference between photographing ranges to make resolution lower in peripheral area than in a central area.SOLUTION: A radiation measuring device obtains images respectively with respect to a plurality of radiation detection element groups disposed at appropriate distances from a pinhole collimator, normalizes the sizes of the images in photographing ranges of the respective radiation detection element groups, and then composes the images obtained from the respective radiation detection element groups.
