The study on a novel radiation dosimetry measuring based on optically stimulated luminescence

The online detecting technology of optically stimulated luminescent (OSL) radiation dosimeter main make use of the OSL characteristics of doping the alkaline-earth metal sulphides, makes the material into the thin films for storing energy from ionizing radiation, the excitation light through optical fibers reached the probe where under radiation field, with a sensitive detection device to read out the radiation dose from storing the OSL material, obtains a novel technology of radiation dose measurement. This technical survey a board dynamic measurement range and a high sensitivity; Storing internal radiation energy can eliminate with the used radiation dose, the equipment is relatively simple and small in size, low power consumption. This device is suitable for measuring the space radiation dose exploration; in additions, it also can be used in IC and the high radiation dose and other dangerous radiation occasions. This device have a good prospect. (authors)
