用热释光技术测量了距广岛原子弹爆炸震源2.05 km处屋顶瓦片样品的γ剂量。还分析了在2.45公里处收集的两个瓦片样品，以检查背景估计的可靠性。2.05公里距离的结果为129 +/- 23 mGy，五个样本的平均值。该值比相应的DS 86估计值大2.2倍。这些结果和文献中的结果表明，在距离广岛震源2.05 km处，DS 86的估计值为实测值的50%或更少。
The gamma ray dose at 2.05 km ground distance from the Hiroshima atomic bomb hypocenter was measured from roof tile samples by a thermoluminescence technique. Two tile samples collected at 2.45 km also were analyzed to check the reliability of the background estimates. The result for the 2.05 km distance was 129 +/- 23 mGy for five-tile sample average. This value is 2.2 times larger than the corresponding DS86 estimate. These results and those in the literature show the DS86 estimate is 50% or less of the measured value 2.05 km from the Hiroshima hypocenter.
