4.9 Radon
One of every five homes tested in a 10-state survey last winter was found to contain health-threatening levels of radon. The survey was conducted in Alabama, Colorado, Connecticut, Kansas, Kentucky, Michigan, Rhode Island, Tennessee, Wisconsin and Wyoming by the respective state governments in cooperation with the Federal agency. Twenty-one percent of the homes tested were found to have levels of radon considered to pose a threat to health under E.P.A. guidelines. This seems to be a problem here in our area.
Radon comes from the natural breakdown of uranium in soil, rock, and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Radon is most often found in indoor environments such as homes, schools, and workplaces. The EPA recommends that all houses be tested for radon levels.
Some Experimental studies have shown that soil ventilation can be effective in reducing radon concentrations in single-family homes. The average post-mitigation radon in the houses was 30 Bq m, an average observed reduction of >90%.
