Abstract: To control and remove radioactive pollution on indoor wall surface, a special injector, a collector and self-crushing decontamination fluid were developed. As a result of performance tests, these specific equipments met the requirements of application considerably well. The decontamination effects of the self-crushing decontamination fluid for radioactive dusts on the surface of concrete, glass, and marble were measured. The results showed that its decontamination efficiency were higher than 85%. Practical applications of this method could be expected.

Key words: radioactive dust, self-crushing decontamination fluid, injector, collector, decontamination efficiency
