Thermoluminescence dosimetry measurements of gamma rays produced by the atomic bomb in Hiroshima were made by the predose technique using eight ceramic samples collected from five buildings located at distances between 1271 and 2051 m from the hypocenter. The results of our measurements are compared to both the newer dose estimates (Dosimetry System 1986) and older dose estimates (Tentative 1965 Doses) for survivors of the Hiroshima atomic bomb. In comparison with the older estimates, our results are larger by a factor of 2.3 at 1271 m and 3.9 at 2051 m. Our results and the newer estimates for Hiroshima differ by a factor of only 1.14 +/- 0.16 on the average.
利用预剂量技术，对从位于距广岛原子弹爆炸中心1271至2051米处的五栋建筑物采集的八个陶瓷样本进行了热释光剂量测定，以测量广岛原子弹产生的伽马射线剂量。我们的测量结果与广岛原子弹幸存者的最新剂量估计值（剂量测定系统1986）和旧的剂量估计值（暂定1965年剂量）进行了比较。与旧的估计值相比，我们的结果在1271米处大2.3倍，在2051米处大3.9倍。我们的结果与广岛的最新估计值平均相差仅1.14±0.16倍。
