Decontamination method of radioactive substance classes, and decontamination for magnetic composite particles and radioactive material such as decontamination system,

摘要

A be capable decontaminating radioactive substances with high efficiency, suitable radioactive substances decontamination system in environmental resistance is high mass treatment, provides a decontamination method of radioactive substances. A radioactive substances decontamination system according to the present invention, radioactive substances such as decontamination magnetic composite particles 1 to capture in a liquid, in a liquid, force integrated to integrated decontamination magnetic composite particles 1 and it means 30. Decontamination magnetic composite particles 1, scavenging compound 18 captures the core part magnetic nanoparticles 10, the radioactive substances in the liquid in the surface layer and, coated magnetic nanoparticles 10 directly capture and magnetic nanoparticles 10 a multilayer structure of the coating layer 15 is substantially formed during the sexual compound 18. .FIELD 3C
