PROBLEM TO BE SOLVED: To provide a simple and low-cost technique for removing both radioactive iodine and radioactive cesium together, which does not require any energy sources such as electric power and capable of taking removed radioactive iodine and radioactive cesium into a solid to trap and stably immobilize the same therein, and also reducing volume of radioactive waste.SOLUTION: A method of removing radioactive iodine and radioactive cesium using a hydrophilic resin composition containing a hydrophilic resin and zeolite is disclosed. The hydrophilic resin contains at least one type of resin chosen from a group of hydrophilic polyurethane resin, hydrophilic polyurea resin, and hydrophilic polyurethane-polyurea resin having a hydrophilic segment and, on a main chain and/or a side chain of the structure thereof, a tertiary amino group and a polysiloxane segment. The hydrophilic resin composition contains at least 1 to 200 pts. mass of zeolite dispersed therein per 100 pts. mass of the hydrophilic resin. |
