Design and Fabrication of Laboratory Pilot for OSL Dosimeter System for Space Applications

OSL dosimeter system was introduced first time in 1963 and it has been used for space application science 2005 by space organizations. In this work we try to design and fabricate this system in Iran for the first time. Basic physical quantum of this system is optically stimulated luminescence. This system consist of OSL material, Optical section for Stimulation and reader section. In this work, first the basic theory of OSL phenomena has been reviewed, then the space applications and the advantage of this system has been compared with other dosimeter system. Afterward laboratory construction of this system and some characterizations of that such as primary calibration by Co-60 source, has been introduced. Finally, results of evaluation of this system shows that, this fabricated system has linear response function in rang of 1-10 Gy.
