| Popis: | 105 The research intends to improve the system of Radio-Photoluminescence Glass Dosimeter (RPLGD). It has significant progress on elevating the ability of laser focusing and the quality of image-forming with coaxial measurement. The results also show that Charge-coupled Device(CCD) and Photomultiplier(PMT) can be switched. Meanwhile, the research enhanced the stability of RPLGD holder that it was obviously shorten the time of focusing and measurement and more convenience to test. For further analysis and detection, the research measured 115 pieces of 1 Gy samples which are 1.5 mm of diameter and 1.8 mm of length in two kinds of experimental modes. To compare with the previous system, the results of the round face measurement with same amount of samples which are within ±5% error in average value were raised from 71% to 75%. To apply the same formula to linear regression analysis, the developed RPLGD has the same linear trending as the previous system. Thus, the research adjusted the relationship between the intensity of the luminescence signal and the radiation dose to make the model much near to the lifetime then examining the doses of cumulative radiation. |
