Abstract
Optically simulated luminescent dosimeter, OSLD, will take place thermo luminescent dosimeter, TLD, to become the main personal dosimeter. Contrast to international world, the basic OSLD researches and applications in Taiwan are still in the starting-up stage. This study developed a Monte Carlo based dose algorithm for optically simulated luminescent ring dosimeter, OSLRD, to solve the miss-estimated dose value due to energy dependence. This algorithm proposed three models dominated by three angles, such as 0, 30, 60 degree, to modify the error due to angular dependence. The dose algorithm developed in this study had passed the verification performed by the National Standard Laboratory, Institute of Nuclear Energy Research, INER. It was recognized that this algorithm can be used to modify the miss-estimated dose due to energy dependence of OSLD. The overall dose errors in the verification were in the range of -11.7 % to 24.5 %. These results meet the requirements (dose error within ±40 %) of Taiwan Accreditation Foundation, TAF, in the test area of externally personal dose estimation.
