Title Occupational exposure of water-plant operators to high concentrations of radon-222 gas
Bibliographic information Aug. 1996, Vol.38, No.8, p.759-764. 19 ref.
Abstract Aeration of water in water treatment plants may lead to the release of dissolved radon-222 gas inside the plant. Measurement of average annual air concentrations of radon-222 in 31 water plants in Iowa, USA revealed that some plants exceeded the maximum permissible concentration established for underground mines. 4 plants were monitored continuously for 3 to 6 days, and weekly exposures for the plant operators were estimated. Because of the short exposure time, none of the exposures examined exceeded the OSHA standard of 4 working-level months. Recommendations include avoiding aeration of ground water inside new and existing plants, ventilation, and monitoring airborne concentrations of radon-222.
