ATSDR Draft Toxicological Profile for Radon_September 2008.pdf

RADON 923. HEALTH EFFECTSChild health data needs relating to exposure are discussed in Section 6.8.1, Identification of Data Needs:Exposures of Children.3.12.3 Ongoing StudiesThe following ongoing studies were identified in the Federal Research in Progress database (FEDRIP2008).Dr. Martha Linet, from the National Cancer Institute Division of Cancer Epidemiology and Genetics, isassessing the modification of risk from smoking intensity using tobacco data from a comprehensive casecontrolstudy of lung cancer in rural China in which high indoor radon levels were associated withincreased risk of lung cancer.Dr. David Mendez, from the University of Michigan, is modifying an existing population-based modelthat predicts tobacco use, radon exposure, and lung cancer mortality. The modified model will be used toelucidate the relative impact and cost-effectiveness of residential radon remediation strategies versussmoking reductions on radon-related lung cancer.Additional research known to be underway includes pooling of results from Iowa and Missouri residentialradon studies using glass-based detectors that are undergoing final calibration (field, personalcommunication) and pooling of results from the residential radon studies that contributed to the results ofKrewski et al. (2005, 2006; North American studies) and Darby et al. (2005, 2006; European studies).***DRAFT FOR PUBLIC COMMENT***
