自切尔诺贝利核电站事故以来，人们已经知道放射性铯往往集中在野生蘑菇中。在福岛第一核电站（FDNPS）事故后的恢复过程中，对蘑菇中放射性铯的活度浓度进行跟踪测量是非常重要的。我们评估了2015年从川内村采集的野生蘑菇中检测到的人工放射性核素（放射性铯）的放射性浓度，川内村距离FDNPS不到30公里，事故发生后4年。我们发现，放射性铯的测定在147的159蘑菇样品（92.4%）。根据日本公民的平均蘑菇消费量（每年6.28公斤），我们计算出的承诺有效剂量范围为<0.001至0.6 mSv。虽然承诺的有效剂量相对有限，但即使居民食用了几次蘑菇，也需要对福岛蘑菇中的放射性铯进行持续监测，以便从核灾难中持续恢复。
Since the accident at the Chernobyl Nuclear Power Plant, it has become well known that radiocesium tends to concentrate in wild mushrooms. During the recovery process after the accident at the Fukushima Daiichi Nuclear Power Station (FDNPS), it is important to perform follow-up measurements of the activity concentrations of radiocesium in mushrooms. We evaluated the activity concentrations of the detected artificial radionuclides (radiocesium) in wild mushrooms collected from Kawauchi village, which is within 30 km of the FDNPS, in 2015, four years after the accident. We found that the radiocesium was determined in 147 of 159 mushroom samples (92.4%). Based on the average mushroom consumption of Japanese citizens (6.28 kg per year), we calculated committed effective doses ranging from <0.001 to 0.6 mSv. Although committed effective doses are relatively limited, even if residents have consumed mushrooms several times, continuous monitoring of the radiocesium in mushrooms in Fukushima is needed for sustained recovery from the nuclear disaster.
