The U.S. Environmental Protection Agency, Consumer Reports and repeated independent studies have shown granite countertops pose no health hazard.<BR/>• EPA stated Friday: “EPA has no reliable data to conclude that types of granite used in countertops are significantly increasing indoor radon levels.” (http://iaq.custhelp.com/cgibin/iaq.cfg/php/enduser/std_alp.php)<BR/>• University of Akron researchers found no threat. (www.marble-institute.com/industryresources/radontesting_u-akron2008.pdf<BR/>• An independent scientific analysis of a variety of studies shows that, accounting for normal airflow in the typical home, radon contributed by granite countertops ranges from 0.01 – 0.02 pCi/L – levels that are 200 to 400 times lower than the EPA guideline of 4 pCi/L.<BR/><BR/>By some measures, the amount of radon emitted by a granite countertop is less than one millionth of that already present in household air from other sources. Many granite countertops do not emit radon at all, and those treated with sealant reduce emissions even further.<BR/><BR/>Tiffany Daniels<BR/>Cohn & Wolfe on behalf of the Marble Institute of AmericaAnonymoushttps://www.blogger.com/profile/05478766721831902692noreply@blogger.com
