The radiation contamination after the Fukushima Daiichi Nuclear Power Plant accident attracts considerable concern all over the world. Many countries, areas, and oceans are greatly affected by the emergency situation other than Japan. An effective remediation strategy is in a highly urgent demand. Though plenty of works have been carried out, progressive achievements have not yet been well summarized. Here, we review the recent advances on the remediation of radiocesium-contaminated liquid waste, soil, and ash. The overview of the radiation contamination is firstly given. Afterwards, the current remediation strategies are critically reviewed in terms of the environmental medium. Special attentions are paid on the adsorption/ion exchange and electrically switched ion exchange methods. Finally, the present review outlines the possible works to do for the large-scale application of the novel remediation strategies.
福岛第一核电站事故后的辐射污染引起了全世界的广泛关注。除日本外，许多国家、地区和海洋都受到了这一紧急情况的严重影响。迫切需要一种有效的修复策略。尽管已经开展了大量工作，但尚未对取得的进展成果进行很好的总结。在此，我们综述了放射性铯污染液体废物、土壤和灰烬修复方面的最新进展。首先介绍了辐射污染的概况。然后，根据环境介质对当前的修复策略进行了批判性综述。特别关注了吸附/离子交换和电开关离子交换方法。最后，本综述概述了新型修复策略大规模应用可能需要开展的工作。
