MAGNETIC COMPOSITE PARTICLES FOR DECONTAMINATION AND METHOD FOR PRODUCING SAME, AND SYSTEM FOR DECONTAMINATING RADIOACTIVE MATERIALS AND METHOD FOR DECONTAMINATING RADIOACTIVE MATERIALS

摘要

Provided is a radioactive substance collecting system and a radioactive substance collecting method which are capable of collecting radioactive substances with high efficiency. The radioactive substance collecting system according to the present invention removes radioactive substances (radioactive cesium 21) contained in a liquid (radioactive substancescontaminated water 20) and includes, as means for removing radioactive substances from the liquid, a radioactive substance trapping composite 1 including at least a magnetic particle 10 and a radioactive substance trapping compound 11 that traps radioactive substances, and magnetic accumulation means 30 for accumulating the radioactive substance trapping composite 1.
