目的福岛第一核电站事故发生至今已有一年半的时间。环境辐射剂量率并不严重，但在福岛县的大部分地区已经确定了现有的暴露情况。尽管人们继续在受污染地区生活和工作，但他们没有获得足够的信息，无法自行减少辐射照射。在这项研究中，我们试图评估辐射屏蔽的效率，通过使用日常用品广泛提供给人们。方法NaI闪烁和盖革-缪勒调查仪被用来测量（1）污染的土壤和（2）土壤覆盖的常用物品。结果在土壤中的深度从表面10 cm，辐射剂量率由3.36 μSv/h降至0.65 μSv/h，计数率由3,120 cpm降至352 cpm。当土壤被日常用品覆盖时，如超过20 mm厚的杂志，聚苯乙烯泡沫板和相同厚度的木板，辐射剂量率和计数率都降低。结论在现有的暴露情况下，为了保护居民免受不必要的辐射照射，用木板或杂志覆盖污染土壤，其中任何一个20 mm厚，有助于减少辐射剂量。
ObjectivesOne and a half years have passed since the Fukushima Daiichi nuclear power plant disaster. The environmental radiation dose rate was not critical, but an existing exposure situation has been identified in a large part of Fukushima Prefecture. Although people continue to live and work in the contaminated area, they are not provided with sufficient information to reduce their exposure to radiation by themselves. In this study, we attempt to evaluate the efficiency of radiation shielding by using everyday items widely available to people.MethodsNaI scintillation and Geiger–Müller survey meters were used to measure the radiation dose of (1) contaminated soil and (2) soil covered with commonly available items.ResultsIn the soil at a depth of 10 cm from the surface, the radiation dose rate decreased from 3.36 to 0.65 μSv/h, and the count rate decreased from 3,120 to 352 cpm. Both the radiation dose rate and count rate reduced when the soil was covered with everyday items, such as a magazine more than 20 mm thick, a polystyrene foam board, and a wooden board of the same thickness.ConclusionsTo protect residents from unnecessary radiation exposure in the existing exposure situation, covering contaminated soil with a wooden board or a magazine, either of them 20 mm thick, is useful to reduce the radiation dose.
