![عکس صفحه اول مقاله: Synthesis and physical characteristics of radiophotoluminescent glass dosimeters Synthesis and physical characteristics of radiophotoluminescent glass dosimeters](/preview/png/1889178.png)
The radiophotoluminescent glass dosimeter (RPLGD) was developed in the late 1950s while the reading technology was not sensitive enough to measure the low radiation dose and glass element sensitivity to radiation was also quite low. In recent years, the development of the pulsed UV laser excitation method which has high measurement accuracy was applied to the RPLGD. In comparison with the thermoluminescent dosimeter, the advantages of the RPLGD are good reproducibility of readout values, long stability, low energy dependence, better dose linearity and capability of repeatable readouts. It could be one of the most important radiation dose measurement instruments in the near future. Hence, some important physical characteristics of glass dosimeters including reproducibility of readout values, dose linearity, accumulative dose measurement, energy dependence and angular dependence were explored. In this study, four series of glass dosimeters were prepared from reagent powders of Na3PO4Na3PO4, Na2CO3Na2CO3, Al(OH)3Al(OH)3, AgCl, and P2O3P2O3. It is necessary to develop the novel compound of RPLGD to measure radiation dose.
