Abstract
Synthesis and characterization of strippable polymeric-gel solution based on a water-soluble polymer (PVA), plasticizing agent (glycerol), and chelating agent (8-Hydroxyquinoline) for the surface decontamination from 137Cs and 60Co was carried out. Decontamination of glass and PVC surfaces was investigated in the present study, as a function of various chelating agents, gel-layer thickness, and radioactivity level. The decontamination efficiency was up to 95% for both radionuclides after 24 h of contact time with the contaminated surface. The obtained results suggest that the decontamination process of 137Cs and 60Co by polymer gel is possible combined by two mechanisms: chemically and physically.
