The studymain objective is to evaluate the association between residential radon exposure and the incidence of lung cancer in Iowa women. Advisories have been issued indicating radon is the second leading risk factor for lung cancer and may be responsible for 7,000 to 30,000 lung cancer deaths annually. To be eligible for inclusion in the study, cases and controls must have resided in their current home for twenty or more consecutive years. Up to seven alpha track radon detectors are placed in each home for one year to measure contemporary radon gas exposure. Several historic radon detectors are employed for one year to measure contemporary and historic radon progeny concentrations.
Additional monitoring is conducted in a subset of homes to examine yearly radon variations.
The radon measurements are linked with historical temporal and spatial participant occupancy patterns to obtain radon and radon progeny exposure estimates. Mammography Surveillance Pilot Study CDMC staff are providing database design and applications support for the Mammography Surveillance Pilot Study being conducted in Scott County, Iowa. Possible environmental risk factors for breast cancer include exposures to xenoestrogens and residential magnetic fields. The Iowa Mammography Surveillance Pilot Study is participating in a national consortium of similar surveillance studies. The consortium is committed to sharing common protocol, study design, and research objectives as well as comparable data collection procedures.
