The readout characteristics of self-fabricated radiophotoluminescent glass dosimeter reading system

• The amount of fluorescence emitted from glass dosimeter was proportional to the radiation dose.
• The glass dosimeter luminescence signals were decayed in the remaining 10% of 10 μS.
• This study successfully completed the self-fabricated radiophotoluminescent glass dosimeter readout system.

The major property of radiophotoluminescent glass dosimeter is its repeatable readout for the radiation measurements. Accordingly, the radiophotoluminescent glass dosimeter system will become one of the important dosimeters for dose measurement in the future. The aims of this study were to develop and characterize the self-fabricated radiophotoluminescent glass dosimeter reader system. The photomultiplier tube, charge-coupled device, nitrogen pulsed laser, band pass filter, 500 nm long pass filter and GD-302 glass dosimeter were used in this study. Based on our study, we found that the values of R-squared for both photomultiplier tube and charge-coupled device in reading system were 0.9968 and 0.9992, respectively, which shows that the relationship between luminescent signals or fluorescence images intensity of glass dosimeter and irradiation dose is direct proportion. These results suggest that the photomultiplier tube and charge-coupled device optical detector can be used in radiophotoluminescent glass dosimeter readout system.
