Phytoremediation, a promising technology using plants to remove radioactive contaminants from the environment or to render them harmless, has become a hot topic in current research.

利用植物修复技术对环境放射性污染进行治理是目前国内外有关学者研究的热点和难点问题。

Its purpose is not to shield radioactive emissions but to prevent the release of radioactive dust and other materials, and to keep out rainwater, which could carry contaminants into the water table.

它的作用不是用来遮挡放射性排放而是阻止放射性烟尘和其它物质的释放，以及遮挡雨水以防止雨水携带污染物流入地下水。

In addition to radioactive contaminants, the material also removes salt and heavy metals from water making it ideal for use in treating water after natural disasters.
