New threshold for deadly radon gas Federal change means thousands of homes once thought safe will soon be considered to pose lung cancer threat Larry Pynn, Vancouver Sun An estimated 500,000 Canadians are living in homes that exceed pending new federal guidelines for radon gas, a naturally occurring radioactive substance described by health officials as a quiet killer and the leading cause of lung cancer after smoking, The Vancouver Sun has learned. -------------------------------------------------------------------------------- The risk of radon and your health Radon's impact on property values Fact Sheet: What is radon gas? -------------------------------------------------------------------------------- http://www.canada.com/vancouversun/news ... 9732fb9b1f Countries such as Australia, Spain, and the United Kingdom already have a standard of 200 becquerels. The U.S. has the lowest of all at 150 becquerels, a guideline adopted in 1986 and described by the Environmental Protection Agency as "a balance between health protection and what is technically feasible." All of which raises the question: Should Canada have acted sooner to lower the radon guideline? Tracy responded from Ottawa that the federal government did not have solid enough evidence to support the lower guideline and did not want to frighten Canadians into making unnecessary improvements to their homes. "Before you impose a heavy burden on the homeowner, make sure there really is a hazard," he said. "Now, we've concluded, yes, indeed, it is a hazard." Acknowledging the U.S. seems to have taken the right

Alzheimer’s & Parkinson’s – Could the Cause be Radon? PDF - Detailed Study Results http://www.radonnews.org/pages/Alzeheim ... nsons.html In a study conducted at the University of North Dakota, researchers discovered that the presence of radioactive radon daughters in the brains of non-smoking persons with Alzheimer’s and Parkinson’s disease was 10 times greater than it was in the brains of persons with no previous evidence of neurological disorders. Professor Glenn Lykken and Dr. Berislav Momcilovic assert their study demonstrates that indoor radon gas has the capacity to irreversibly infest the brain with the poisonous progeny of radioactive heavy metals. University of North Dakota researchers are looking for more funding to continue their research.

Recent results from the largest radon studies ever conducted in North America and Europe show six to 15 percent of all lung cancers are caused by exposure to the gas.

http://www.cheec.uiowa.edu/misc/radon.html The Iowa Radon Lung Cancer Study was a large-scale epidemiology study initiated in 1993 and funded by the National Institute of Environmental Health Sciences (NIEHS). The study assessed the risk posed by residential radon exposure. The 5-year study was performed in Iowa and the participants were women throughout Iowa who lived in their current home for at least 20 years. Over a thousand Iowa women took part in the study. Four hundred and thirteen of the participants were women who had developed lung cancer, the remaining 614 participants were controls who did not have lung cancer. The study was limited to women, because they historically tend to spend more time at home and they have less occupational exposure to other lung carcinogens. The epidemiologic study was performed in Iowa for several reasons. Iowa has the highest average radon concentrations in the United States. In addition, women in Iowa tend to move less than most other states, which makes calculation of their past radon exposure easier. Iowa was also selected because it has a quality National Cancer Institute SEER cancer registry, which helped us identify women who developed lung cancer. Close to 60% of the basement measurements for both cases (participants with lung cancer) and controls (participants without lung cancer) exceeded the EPA's action level. Twenty-eight percent of the living areas for the controls and 33% of the living areas for the cases exceeded the EPA's action level of 4 pCi/L. The Iowa Radon Lung Cancer Study had several strengths. First, independent pathologic review was performed for 96 percent of the cases. Second, the study was carried out in Iowa, which has the highest mean radon concentrations in the United States. Third, the high radon concentrations in conjunction with a strict quality assurance protocol contributed to accurate and precise radon measurements. Fourth, the IRLCS criteria requiring occupancy in the current home for at least the last 20 years eliminated the need to impute radon measurements from missing homes. Fifth, the linkage between radon measurements and retrospective participant mobility allowed for a refined exposure estimate. The IRLCS risk estimates are in general agreement with the National Research Council's predicted cancer risk associated with indoor radon exposure. Overall, the risk estimates obtained in this study suggest that cumulative radon exposure in the residential environment is significantly associated with lung cancer risk
