Abstract

The paper presents results of measurements of the efficiency of retention of radon decay products, occurring as radioactive aerosols, by anti-dust masks. The efficiency of three types of masks: PM-1, PM-3, PP-2 "Delta" was studied under various conditions of equilibrium between radon and products of its decay in the air. It was concluded that the efficiency of retention of radon decay products, occurring as radioactive aerosols, by the mentioned types of masks, comes to 75--87%. Anti-dust PM-1 (F-14 filter) and PM-3 (F-13 filter) masks are recommended as most efficient.
