輻射工作人員於從事輻射作業時必須全程配戴人員劑量計,光激發光劑量計(optical stimulated luminescence dosimeter, OSLD)為目前發展成熟的新型輻射劑量計技術。光激發光劑量計具有可以重複計讀、無須加熱迴火及方便攜帶型的計讀儀器。目前國際較少針對佩章型光激發光劑量計於高能量輻射場域及佩章外盒特性進行研究。
本研究使用放射腫瘤科常用之高能直線加速器輸出光子及電子射束進行三氧化二鋁作為晶體材料的佩章型光激發光劑量計 (InlightTM OSLD),搭配兩種佩章外盒OSLD hole body holder及Inlight model 2進行劑量照射比較。以一批全新劑量計量測其能量依存性、角度依存性、劑量計線性度、晶格穩定性、消光效應、漂白結果。
研究結果顯示,光激發光劑量計搭配兩種佩章外盒在光子射束與電子射束皆具有良好的劑量線性度。無佩章外盒之光子射束能量依存性在1%內,搭配兩種佩章外盒外盒在3%~5%範圍。無佩章外盒之電子射束能量依存性6%內,搭配兩種佩章外盒外盒在1%~4%範圍。有無佩章外盒在光子射束照射角度60度及240度皆有較大的角度依存性;電子射束照射無劑量計外盒最大角度依存性在30度,兩種佩章外盒則在210度。在最初照射劑量計晶格呈現不穩定,劑量計存放達一個月以上之消光性為 3%並具有重複使用的特性。
佩章型光激發劑量計適用於高能量環境輻射場域作為人員劑量計使用,搭配劑量計外盒配戴時須正確配戴,研究成果可供輻射工作人員及研究人員挑選劑量計做為參考。

Radiation workers must wear dosimeters throughout the entire process of radiation work. Optical stimulated luminescence dosimeter (OSLD) is a new and mature radiation dosimeter technology. The optical stimulated luminescence dosimeter has a repeatable meter reading, no need for heating and tempering, and a portable meter reading instrument. At present, there are few researches on the characteristics of the badge-type optical stimulated luminescence dosimeter in the high-energy radiation field and the outer box of the badge.
In this study, the photons and electron beams of high-energy linear accelerators commonly used in radiation oncology were used to carry out a badge-type photo-excited light dosimeter (InlightTM OSLD) using Al2O3:C as the crystal material, with two badge outer boxes OSLD hole body holder and Inlight model 2 for comparison of dose irradiation. The energy dependence, angle dependence, dosimeter linearity, crystal stability, extinction effect, and bleaching results were measured with a new dosimeters.
The research results show that the photon beam and electron beam have good dose linearity in both photon beam and electron beam. The photon beam energy dependence of the outer box without the badge is within 1%, and the range of 3%~5% with the outer box of the two badges. The electron beam energy dependence of the outer box without the badge is within 6%, and the range of 1%~4% with the outer box of the two badges. With or without the badge box, the photon beam irradiation angle of 60 degrees and 240 degrees has a large angle dependence; the electron beam irradiation without dosimeter box has a maximum angle dependence of 30 degrees, and the two badge boxes are in 210 degrees. The crystal OF the dosimeter appears unstable at the initial exposure. The dosimeter has an extinction of 3% for more than one month and is reusable.
The Optical Stimulated Luminescence Personal Dosimeter is suitable for use as a personnel dosimeter in high-energy environmental radiation fields. It must be worn correctly when it is worn with the dosimeter badge. The research results can be used by radiation workers and researchers to select dosimeters for reference.
