Abstract: To explore new type of radioactive contamination protection technology and find more efficient, environmentally sound,practical methods, radioactive contamination protection tests were conducted, with a strippable protective coating of Protectapeel E106 produced by Spraylat International Limited, UK, on walls, floors and equipment surfaces in the controlarea of AC radioactive maintenance workshop at Hongyanhe NPP. A method of manually pressure-regulating spraying was adopted with a small air gun, Model W-7-3S, manufactured by Iwata Corporation, Japan. The results show that, as a radioactive contamination protective medium, Protectapeel E106 strippable protective coating can play a better role in radioactive contamination protection of walls, floors and equipment surfaces.
