2002年3月至11月期间（233天），利用7个LiF：Mg，Ti（LiF-700）热释光（TL）探测器对国际空间站俄罗斯段上不同面板的吸收剂量和平均线性能量转移（LET）进行了评估。提出了一种修正航天器辐射气候中TL效率的吸收剂量测量值的方法。平均LET是从TL-700辉光曲线中的高温TL发射确定的，并用作TL效率校正中的参数。根据屏蔽分布，效率校正吸收剂量在327号面板（芯块天花板）的154 +/- 5 microGy d（-1）和110号面板（芯块中心轴，地板）的191 +/- 3 microGy d（-1）之间变化。通过使用详细的屏蔽分布和轨道参数作为输入，将实验数据与模型计算进行了比较。
Absorbed dose and average linear energy transfer (LET) were assessed by means of (7)LiF:Mg,Ti (TLD-700) thermoluminescent (TL) detectors for different panels on-board the Russian Segment of the International Space Station in the timeframe between March and November 2002 (233 d). A technique is presented to correct the measured absorbed dose values for TL efficiency in the radiation climate on-board the spacecraft. Average LET is determined from the high-temperature TL emission in the TLD-700 glow curve and used as a parameter in the TL efficiency correction. Depending on the shielding distribution, the efficiency-corrected absorbed dose varies between 154 +/- 5 microGy d(-1) in panel no. 327 (core block ceiling) and 191 +/- 3 microGy d(-1) in panel no. 110 (core block central axis, floor). The experimental data are compared with the model calculations by using detailed shielding distributions and orbit parameters as inputs.
