Employee exposure to (222)Rn and (220)Rn in three fish culture stations in Pennsylvania

Employee exposures to Rn and Rn were measured in three Commonwealth fish hatcheries using specially designed personal dosimeters to determine whether remediation might be necessary. Employees utilizing the hatch house would wear the dosimeter and keep track of their time in the hatch house. Area det...

Summary:Employee exposures to Rn and Rn were measured in three Commonwealth fish hatcheries using specially designed personal dosimeters to determine whether remediation might be necessary. Employees utilizing the hatch house would wear the dosimeter and keep track of their time in the hatch house. Area detectors were also deployed full time in each hatch house. Exposure measurements were compared to U.S. Nuclear Regulatory Commission, U.S. Environmental Protection Agency, and Occupational Safety and Health Administration exposure limits. All measured employee exposures to Rn and Rn were very low and well below currently established regulatory limits. However, hatch house radon concentrations are significantly elevated above the U.S. Environmental Protection Agency residential guideline of 148 Bq m.
