| Abstract:: |
| A nuclear accident likely leads to the leakage of radiocesium to a large degree, which could poses threatens to the environment and human health. Hence, it is very important to remove radiocesium ion from the environment and human body in the aftermath of a nuclear accident. In this review, the new progress of radiocesium ion removal in a nuclear emergency is discussed. The main technique to reduce soil pollution is to remove and purify topsoil. The methods of purification include leaching method, electrokinetic process and soil immobilization. The technique to remove radiocesium from water is mainly via adsorption. Common adsorbents include crown ether, calix ether, ammonium molybdophosphate and Prussian blue. Radiocesium removal from human body is mainly via oral administration of Prussian blue at fractioned doses in a timely manner but spents a relatively long response time, possibly accompanied with some severe side effects, like hypopotassemia and physical damage of digestive tract. Therefore, new techniques are still in need of development to remove radiocesium ion from human body more effectively. |
