本研究目的分為三個部分，一為解析現有商業化光刺激發光劑量佩章(光子、中子、環境)之劑量演算流程，二為驗證光刺激發光中子劑量佩章的演算法並且和實際照射計讀結果進行比較驗證，三為探討使用光刺激發光環境劑量佩章與人員光子劑量佩章進行劑量監測之特性差異探討。本研究分析Landauer公司三種佩章演算法及探討三者之特性差異；參考商業化人員中子劑量佩章的演算法，建置簡易的驗證程式，提供輸入原始計讀數據計算劑量結果，將此結果與實際照射之結果進行比較驗證。當混合輻射場中之中子劑量低於光子劑量一定比例時，演算法之結果會有將中子劑量忽略的情況。為瞭解真實中子劑量情況，本研究將原OSLN演算法修改，並進行實際照射測試驗證，測試結果顯示修改後的中子劑量與修改前相比，誤差下降，並符合國內人員劑量計能力試驗之要求，相關結果可供使用OSLN之人員劑量實驗室作為OSLN計讀結果的驗證工具。此外，本研究比較OSLD與環境佩章(OSLE)於空間環境中或假體的條件下之量測結果，使用OSLD監測環境劑量，在空氣中OSLD缺少來自假體的回散射劑量，會因此低估約13％；反之，OSLE後方使用15公分假體或物體監測人員劑量則會高估約11％；在空氣中OSLE的劑量會接近在15公分假體OSLD的劑量。雇主若要使用環境監測代替人員劑量監測，使用放置於空間環境之OSLE量測結果不用經過轉換即可推估人員劑量。

The purpose of this study is divided into three parts. First, analyzed the dose algorithms of the commercial OSL badges, including OSLDs, OSLNs and OSLEs (Landauer Co.). Second, verified of the commercial OSLN algorithm. Third, discussed the characteristic difference of dose monitoring using OSLDs and OSLEs. This study analyzed dose algorithms of three Landauer badges and discussed the characteristic difference. The commercial OSLN algorithm was referred to design a program to input the original reading results and calculate dose and compare these results with the irradiated dose. It was found that the algorithm may ignore neutron dose when it was lower than the photon dose of a certain ratio. In order to realize the true neutron dose, this study revised the original OSLN algorithm and verified. Results showed that the revised algorithm had a lower error and achieved the requirements of the personnel dosimeter capability test. Relevant results can be used as a tool for verifying the results of OSLN readings. In addition, the measurement results of the OSLDs and OSLEs with or without the phantom were compared. Using OSLDs to monitor the environmental dose, due to the lack of backscatter in the air, so it would be 13% underestimated; on the contrary, using a 15 cm phantom or object behind the OSLE to monitor the personnel dose would be 11% overestimate. The dose of OSLE in the air would be close to the dose of OSLD at 15 cm phantom. The results show that if owners want to replace personnel monitoring by environmental dose monitoring, the results of the OSLEs placed in the environment can estimate personnel dose without conversion.
