福岛第一核电站(DNPP)事故导致大量放射性物质释放到环境中。释放的高挥发性裂变产物，如129mTe，131I，134Cs，136Cs和137Cs被发现广泛分布在日本东部的福岛及其邻近的县。然而，事故发生近一年后，非挥发性氡系元素，特别是钚同位素的释放仍然不确定。本文报道了福岛核电站西北部和南部20-30 公里区域钚向大气释放和地面沉积的同位素证据。福岛核电站事故的高活度比241Pu/239+240Pu(>；100)突显了长期241Pu剂量评估的必要性，以及241Am的内在研究结果对反应堆损坏的评估具有重要意义，并对除污策略具有重要意义。
The Fukushima Daiichi nuclear power plant (DNPP) accident caused massive releases of radioactivity into the environment. The released highly volatile fission products, such as 129mTe, 131I, 134Cs, 136Cs and 137Cs were found to be widely distributed in Fukushima and its adjacent prefectures in eastern Japan. However, the release of non-volatile actinides, in particular, Pu isotopes remains uncertain almost one year after the accident. Here we report the isotopic evidence for the release of Pu into the atmosphere and deposition on the ground in northwest and south of the Fukushima DNPP in the 20–30 km zones. The high activity ratio of 241Pu/239+240Pu (> 100) from the Fukushima DNPP accident highlights the need for long-term 241Pu dose assessment, and the ingrowth of 241Am. The results are important for the estimation of reactor damage and have significant implication in the strategy of decontamination.
