Abstract: The disclosed dosimeter system includes a dosimeter and a reader, the dosimeter including a protective outer container and a support for elements sensitive to radiation, the reader including a frame and a mechanism for receiving the dosimeter. The frame has a cover for supporting measurement devices and a source, and a base for guiding the mechanism which receives the dosimeter. The dosimeter support includes a casing having a movable body for the sensitive elements. The mechanism of the reader has a first shuttle which separates the casing from the body to lock the casing and convey the body and casing to a measurement position, and a second shuttle for immobilizing the body. The system provides for automatic opening, closing and reading of the dosimeter.
