The present invention intends to provide a method for removing radioactive cesium, or radioactive iodine and radioactive cesium that is simple and low-cost, further does not require an energy source such as electricity, moreover can take in and stably immobilize the removed radioactive substances within a solid, and can reduce the volume of radioactive waste as necessary, and to provide a hydrophilic resin composition using for the method for removing radioactive cesium, or radioactive iodine and radioactive cesium, and the object of the present invention is achieved by using a hydrophilic resin composition containing: at least one hydrophilic resin selected from the group consisting of a hydrophilic polyurethane resin, a hydrophilic polyurea resin, and a hydrophilic polyurethane-polyurea resin each having at least a hydrophilic segment; and a clay mineral dispersed therein in a ratio of at least 1 to 180 mass parts relative to 100 mass parts of the hydrophilic resin.
本发明旨在提供一种去除放射性铯或放射性碘和放射性铯的方法,该方法简单、成本低,而且不需要电力等能源,还能将去除的放射性物质吸收并稳定地固定在固体内,并能根据需要减少放射性废物的体积,并提供一种用于去除放射性铯或放射性碘和放射性铯的方法的亲水性树脂组合物,本发明的目的是通过使用一种亲水性树脂组合物来实现的,该树脂组合物含有:至少一种亲水性树脂,选自由亲水性聚氨酯树脂、亲水性聚脲树脂和亲水性聚氨酯-聚脲树脂组成的组,每种树脂都至少具有一个亲水段;以及以相对于 100 质量份的亲水性树脂至少 1 至 180 质量份的比例分散在其中的粘土矿物。
