This video discusses the testing conducted by Environmental Health and Engineering resulting from erroneous media reports stating that granite countertops could be dangerous as a result of radon emissions.
A major study by one of the world's leading environmental research firms shows that in the most common types of granite, there is significantly less radon exposure than the background levels you are exposed to outdoors.
Based on new peer reviewed and published research that reviewed of over 500 measurements of radon emissions from granite, Environmental Health & Engineering, Inc. of Needham, MA reported the following: 1.Radon emissions were 300 times lower than levels of radon in outdoor air. 2.Radon emissions were 1000 times below the average concentration of radon found in the air in U.S. homes. 3.Radon emissions were 3000 times less than the action level for indoor air recommended by the U.S.EPA.
Final analysis: Information available at the present indicates that radon levels associated with granite countertops in homes are low in comparison to background levels.
