When radon was found to be a ubiquitous indoor air pollutant, however, it raised a more widespread alarm for public health.To develop appropriate public policy for indoor radon, decisionmakers need a characterization of the risk of radon exposure across the range of exposures people actually receive. In response, the BEIR VI committee has developed a mathematical model for the lung cancer risk associated with radon, incorporating the latest information from epidemiology and scientific studies. In this book the committee provides a fresh assessment of exposure-dose relationships. The volume discusses key issues--such as the weight of biological evidence and extrapolation from radon-exposed miners to the larger population--in estimating the risk posed by indoor radon. It also addresses such uncertainties as the combined effects of smoking and radon and the impact of the rate of exposure. The committee considered the entire body of evidence on radon and lung cancer, integrating findings from epidemiological studies with evidence from animal experiments and other lines of laboratory investigation. The conclusions will be important to policymakers and environmental advocates, while the technical findings will be of interest to environmental scientists and engineers. 410 0$aBEIR (Series) ;$v6. 606 $aRadon$xHealth aspects 606 $aRadon$xToxicology 606 $aRadon$xPhysiological effect 606 $aRadiation carcinogenesis 606 $aIndoor air pollution$xHealth aspects 606 $aHealth risk assessment 610 $aRadon 610 $aChemicals 610 $aIndoor Air Pollution 610 $aHealth Risk Assessment 610 $aScience 610 $aMedical 615 0$aRadon$xHealth aspects. 615 0$aRadon$xToxicology. 615 0$aRadon$xPhysiological effect. 615 0$aRadiation carcinogenesis. 615 0$aIndoor air pollution$xHealth aspects. 615 0$aHealth risk assessment. 676 $a363.17/99 712 02$aHealth Risks of Exposure to Radon Committee, 712 02$aLife Sciences Commission, 712 02$aDivision on Earth and Life Studies Staff, 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910778668503321 996 $aHealth effects of exposure to radon$93740843 997 $aUNINA
