蘑菇被认为是切尔诺贝利核电站（CNNP）事故释放的放射性铯活性浓度造成内部辐射暴露的主要贡献者之一。我们评估了2015年从乌克兰日托米尔地区Korosten和Lugine采集的野生蘑菇中人工放射性核素（放射性铯）的活性浓度，该地区距离CNPP 120公里。127份香菇样品中有110份检出铯-137，检出率为86.6%。根据平均食用量（每年5公斤），我们计算出承诺有效剂量范围为0.001-0.12毫西弗。即使在事故发生30年后，铯-137仍然存在于野生蘑菇中，但承诺的有效剂量受到食用受污染蘑菇数量的限制。然而，只要存在食用受污染蘑菇的可能性，仍有必要对核事故影响的周边地区进行内照射评价和环境放射性评价，以缓解内照射的焦虑。
Mushrooms are recognized as one of the main contributors to internal radiation exposure from the activity concentration of radiocesium released by the accident at the Chernobyl nuclear power plant (CNNP). We evaluated the activity concentrations of the artificial radionuclides (radiocesium) in wild mushrooms collected in 2015 from Korosten and Lugine, Zhitomir region, Ukraine, located 120 km away from the CNPP. Cesium-137 was detected in 110 of 127 mushroom samples (86.6%). Based on the average mushroom consumption (5 kg per year), we calculated committed effective doses ranging from 0.001–0.12 mSv. Cesium-137 remains in the wild mushrooms even 30 years after the accident, but the committed effective doses are limited by the amount of contaminated mushrooms consumed. However, evaluation of internal radiation exposure and assessment of environmental radioactivity in the surrounding area affected by the nuclear accident are still necessary in order to relieve anxiety about internal radiation exposure, as long as the possibility of consumption of contaminated mushrooms remains.
