自主无人直升机（AUH）测量是监测环境剂量当量率分布的有用工具。然而，AUH调查方法是针对农业用地等平面透水领域开发的，其在城市地区的适用性尚不明确。本研究通过对郊区住宅用地和农用地的AUH和地面调查结果进行对比，探讨了AUH的适用性。在与土地利用无关的范围内，两项调查的结果在2因子范围内基本一致，该因子与平面透水田报告的因子相同。这些结果表明AUH调查在城市地区是适用的。AUH调查的测量不确定性在很大程度上受到地面上环境剂量当量率的局部和局部分布以及视场差异的影响，而不是受到土地使用的影响。
An autonomous unmanned helicopter (AUH) survey is a useful tool for monitoring the distribution of ambient dose equivalent rates. However, the AUH survey method was developed for plane permeable fields such as agricultural land, and its applicability to urban areas is unclear. In this study, the applicability was investigated by comparing the results of AUH and ground-based surveys conducted in suburban areas, including residential and agricultural lands. The results of both surveys broadly agreed with each other within a factor of 2 in the range independent of land use, and the factor was the same as that reported for plane permeable fields. These results suggest that AUH surveys are applicable in urban areas. The measurement uncertainty of the AUH survey was largely affected by the patchy and local distribution of ambient dose equivalent rates on the ground and differences in the fields of view, rather than land use.
