RADIOACTIVE IODINE ADSORBENT, AND METHOD FOR TREATING RADIOACTIVE IODINE

摘要

Provided is a radioactive iodine adsorbent capable of adsorbing radioactive iodine more effectively than in the conventional art, and removing hydrogen, which is a factor in nuclear reactor accidents. A granulated radioactive iodine adsorbent of zeolite X, wherein ion exchange sites of the zeolite X are substituted with silver so that a size of minute pores of the zeolite X is suited to a size of a hydrogen molecule, and the radioactive iodine adsorbent has a silver content of 36 wt % or more when dried, a particle size of 10×20 mesh, a hardness of 94% or more, and a water content of 12 wt % or less when dried at 150° C. for 3 h and thereby reduced in weight.
