Title Removal of radon daughter aerosols from mine air by filtration
Bibliographic information June 1994, Vol.153, No.393, p.362-364. Illus. 9 ref.
Abstract Respirator filters and filtering facepieces were tested for penetration of radon daughter aerosols; tests were carried out in a fluorspar mine and in the laboratory. Respirators with a filtration efficiency high enough for them to be considered suitable for use against toxic dusts generally reduced radon daughter levels by 90% or more, although nuisance dust masks were ineffective. Comparison between on-site tests and tests with a standard aerosol showed that respirators that satisfy an existing standard could be expected to give reasonable protection against radon daughters.
