[en] These proceedings provide a summary of papers presented at the seventh annual American Statistical Association (ASA) Conference on Radiation and Health. Sessions were scheduled for mornings and evenings with ample time for discussion, thus encouraging communication between scientists, from a variety of disciplines, working on problems related to the health effects of ionizing radiation. The 1987 conference focused on lung cancer risks, especially lung cancer risks due to radon. The BEIR IV report, which addresses health risks of radon and other internally deposited alpha-emitters, was summarized early in the conference. Results of analyses of data on miners in Colorado and in New Mexico were presented as well as analyses of combined data from several studies, which are used as the basis of estimates in the BEIR IV report. Statistical issues related to appropriate analysis of chronic exposure and of smoking data received considerable attention and discussion. Papers describing models for lung cancer risks based on exposure to cigarette smoke, radiation, and other substances provided insights into general understanding of lung cancer mechanisms. Carcinogenic models were also the subject of a presentation on radiation-induced skin cancer in humans and animals. In addition, relevant data on animal experiments involving radon exposure were summarized
