摘　　要：核武器试验、核废料泄漏与核电站事故等造成的放射性污染是全世界关注的热点问题之一。铯-137(^(137)Cs)作为一种半衰期长达30 a、生物毒性大且易进入食物链的放射性核素,在环境中积累后严重威胁生态系统安全和人类健康。笔者详细总结了^(137)Cs在土壤中的分布和吸附行为、植物对^(137)Cs的吸收转运以及^(137)Cs污染土壤的主要修复技术,以期为我国提升放射性污染问题的应对能力提供重要参考。The radioactive contamination mainly caused by nuclear weapon test,nuclear waste leakage and nuclear power plant accident is one of the hot issues concerned worldwide.As a radionuclide with a half-life of more than 30 years,^(137)Cs is highly toxic and easy to enter the food chain,and its accumulation in the environment poses a serious threat to the ecosystem security and human health.This review summarizes the distribution and sorption behavior of ^(137)Cs in soil,uptake and transport of ^(137)Cs by plants,as well as main remediation technologies of ^(137)Cs contaminated soil.The purpose of this article is to provide important references for improving the response capacity of radioactive contamination problems in China.
