ADSORBENT FOR RADIOACTIVE IODINE, AND RADIOACTIVE IODINE REMOVAL APPARATUS

摘要

A radioactive iodine removal apparatus 10 applying a radioactive iodine adsorbent according to an embodiment of the present invention includes an iodine filter 15 that is provided in a chamber 13 of a duct 12 to which flue gas 11A containing radioactive iodine is fed, and includes a radioactive iodine adsorbent 14 that adsorbs radioactive iodine contained in the flue gas 11A. The radioactive iodine adsorbent 14 includes a carrier constituting a matrix and an impregnated substance with which the carrier is impregnated. The impregnated substance contains at least TEDA, and an impregnated amount of the TEDA is from 3.0% by mass to less than 10.0% by mass.
