In this work TLD-200 (CaF₂:Dy) chips were used to measure the gamma-ray doses in a PMMA phantom exposed to the BNCT beam at Tsing Hua Open-pool Reactor (THOR). The self-irradiation component induced by the decay of Dy-165 was corrected. The neutron dose contamination was less than 0.3%. The Dy content in the TLD-200 chip was determined by using the modified absolute calibration method of NAA. The self-irradiation TL signal was also applied for the in situ calibration.

使用TLD-200测量BNCT束中的伽马射线剂量和中子活化。

在这项工作中，使用TLD-200（CaF ₂：Dy）芯片来测量在清华露天反应堆（THOR）暴露于BNCT光束的PMMA体模中的伽马射线剂量。校正了由Dy-165衰变引起的自辐照分量。中子剂量污染小于0.3％。使用改良的NAA绝对校准方法确定TLD-200芯片中的Dy含量。自辐照TL信号也用于原位校准。
