Protection against radon progeny inhalation using filter type respirators
The efficiencies of several respiratory protective devices in removing the airborne radon daughter activity found in underground uranium mines were determined under standardized test conditions. The protection afforded to working uranium miners by simple filter respirators was estimated by comparison in vivo counting of the internally deposited RaC activity present in the respiratory systems of miners at the end of the working shift. The mean protection efficiency obtained was 85.2 {+-} 13.8%, based on in vivo counts of 21 miners. The problem of providing adequate respiratory protection for underground uranium miners is discussed and a suggested list of criteria for respiratory design is given.
