Abstract
In a radiation dose reading apparatus for a fluorescent glass element which was exposed to ionizing radiation and which is subjected to ultraviolet light radiation so as to cause fluorescence with an intensity depending on the radiation dose received by the glass element wherein the radiation dose is determined from the intensity of the fluorescence emitted from the glass elements detecting face, a fluorescence diaphragm arrangement is provided so as to overlay the glass element detecting face and is movable thereon for changing the fluorescence detecting areas and a fluorescence intensity reading device is provided for determining fluorescence intensity distribution and the glass element detecting face.
