Abstract
A dose reading device comprises: an ultraviolet irradiating section for irradiating an ultraviolet laser beam forming an excitation light source for fluorescent glass elements X; a fluorescence detecting section for detecting a radiation exposure dose from the intensity of fluorescence generated by a fluorescent glass element X; a magazine conveying section for conveying a magazine capable of accommodating a plurality of fluorescent glass elements X to a position for measurement by the fluorescence detecting section a dark box for accommodating the magazine conveying section and the fluorescence detecting section a first shielding plate 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 for shielding fluorescence from the fluorescent glass elements X other than the fluorescent glass element X under measurement; and first and second slit plates for transmitting only ultraviolet light that is directed at the fluorescent glass element X under measurement.
