• 中文摘要： 本文探討以氟化鋰熱發光劑量計700型，做為偵測人員貝他劑量的可行性。由於體外貝他射源包括點、面、體等各種類別，因此本文使用溶液法、鈾盤法、二次標準射源法等三種方法，校正厚度為0.38與0.9毫公分的兩系列熱發光劑量計。研究項目包括這些劑量計受貝他能量的影響、角度影響、以及劑量計結構及環境等因素的影響。研究的目的，在於評估深度為7 mg/（無衣物覆蓋）及50 mg/（有衣物覆蓋）之皮膚的劑量。
• 英文摘要： Studies on the personnel beta-ray dosimetry based on the LiF TLD)-700 dosimeters have been made.The calibration of two sets of dosimeters of thickness 0.38 mm and 0.9 mm was carried out with threedifferent methods, namely, the immersion technique, the natural uranium slab and the PTB secondarystandard unit. The energy and the angular dependences for the response of these dosimeters and othercorrection factors have been considered. The transmission factor, the relative response factor, together withthe calibration results for the source were used to assess the beta dose in different tissuedepths, e.g. 50 mg/ and 7 mg/ corresponding to the depths of skin with and without the protectingclothing.
