2011年的福岛第一核电站事故向环境中释放了许多放射性元素，污染了大量土壤。目前，有1400万立方米的污染土壤计划用于临时储存，并计划在2045年之前最终处置这些土壤。将来，核电站的退役将产生大量的放射性废物。因此，减少约占废物90%的受污染土壤的体积是一个需要在工厂退役的同时解决的问题。由于大多数放射性核素在事故发生后的十年中已经衰变，放射性Cs（特别是137Cs）是需要从废物中去除的元素之一。本文综述了放射性铯污染土壤减容技术的研究进展，以及对土壤中放射性铯存在的认识。
The accident at the Fukushima Daiichi Nuclear Power Plant in 2011 released many radioactive elements into the environment, contaminating a large amount of soil. Currently, 14 million m3of contaminated soil is scheduled for interim storage, and the final disposal of the soil is planned by 2045. In the future, the decommissioning of the plant will generate a great amount of radioactive waste. Therefore, reduction of the volume of contaminated soil, which accounts for ~90% of the wastes, is a problem that needs to be addressed in parallel with the decommissioning of the plant. Since most of the radionuclides have decayed in the decade since the accident, radioactive Cs (especially137Cs) is one element that needs to be removed from the wastes. This review summarizes the progress of volume reduction technology for soil contaminated with radioactive Cs and an understanding of the existence of radioactive Cs in the soil.
