1991 Comparative Dosimetry of Radon in Mines and Homes makes it desirable and feasible to proceed with Phase II-a comprehensive reanalysis of health risks associated with radon. The committee based this judgment on
The completion of a joint analysis by Jay Lubin and his colleagues at the National Cancer Institute of data from 11 cohorts of underground miners (including 68,000 miners who experienced over 2,780 lung cancer cases in comparison with the 22,190 miners who experienced 360 lung cancer deaths in the four cohort studies of BEIR IV) that offers a new risk model and strengthens the basis for quantifying indoor (residential) radon as a public-health problem.
New experimental and epidemiologic evidence of an effect of exposure rate on -particle carcinogenesis, such as from the laboratories of Richard Miller, David Brenner, Eric Hall, Helen Evans, and Mortimer Elkind.
Reports of several completed studies, including the recent report of a large study in Sweden by Goran Pershagen and colleagues and the projected completion and publication of additional case-control studies of residential exposure and lung cancer in Europe and the United States during the next 2 years.
New evidence from the study of miners that the interaction of smoking and radon might be less than multiplicative.
Further information relevant to the dosimetry of radon in mines and homes. This information emerges from new instrumentation for field measurements of the concentration and activity-size distributions of radon progeny developed in the laboratory of Philip Hopke and the application of noninvasive methods for monitoring ventilation in the field by Jonathan Samet and others.
New evidence of the potential importance of other factors in
