Abstract

Radioactive contamination caused by nuclear leakage accidents and radioactive source diffusion accidents will pose a threat to the environment and public safety. In order to remove the contamination, an emergency decontamination technique based on strippable coating was studied. The strippable coating takes acrylate emulsion as the main film forming agent and lauryl sodium sulphate as surfactant. The decontamination performance and application dosage of the coating were tested. At the application dosage of 2.5 kg m−2, the single decontamination rate reached 92.26% for uranium dust on concrete surface, which indicates this technology is a promising method for engineering decontamination.
