• Description:
  Estimates were made of quality factors (radiation weighting factors) for radon progeny, and the ratio of quality factors for radon progeny for miners and for home residents, based on data from the C3H10T1/2 oncogenic transformation system at linear energy transfers ranging from 3 to 475 kiloelectron volts/micrometer. The best estimate for the quality factor for radon progeny was significantly lower than those (20 to 25) currently used in estimating lung cancer mortality due to radon (10043922). The best estimate for home dwellers was around 10. The best estimate for the quality factor for home dwellers was about 13% more than for miners. Therefore, the effective K-factor to convert from effective dose/Working Level Month (WLM) in the home to effective dose/WLM in the mine would need to be increased by this factor. The author concludes that a dosimetrically based estimate of radon induced mortality would be about 35,000 per year in the United States, rather than a value of about 70,000 obtained using Hiroshima/Nagasaki based risk estimates and a quality factor of 20. The 35,000 value, while still larger than the miner based values of around 20,000, is much closer than the 70,000 figures. The author notes that the dosimetric and epidemiologically based risk estimates are partially reconciled by these results. [Description provided by NIOSH]
