Dose reading device and dose reading magazine

摘要

A dose reading device comprises: an ultraviolet irradiating section 40 for irradiating an ultraviolet laser beam forming an excitation light source for fluorescent glass elements X; a fluorescence detecting section 50 for detecting a radiation exposure dose from the intensity of fluorescence generated by a fluorescent glass element X; a magazine conveying section 30 for conveying a magazine 10 capable of accommodating a plurality of fluorescent glass elements X to a position for measurement by the fluorescence detecting section 50; a dark box for accommodating the magazine conveying section 30 and the fluorescence detecting section 50; a first shielding plate 31c set at a non-perpendicular angle to the light axis of the ultraviolet laser beam having passed through the fluorescent glass element X; a second shielding plate 31e for shielding fluorescence from the fluorescent glass elements X other than the fluorescent glass element X under measurement; and first and second slit plates 41a, 42a for transmitting only ultraviolet light that is directed at the fluorescent glass element X under measurement.
