Radon in Granite. Facts or Fiction |
Radon Facts or Fiction
In the recent time some information has
circulated online that has created consumer concern about radiation
levels occurring in natural granite used for residential
countertops. The report suggests some countertops may pose health
risks, ignoring years of legitimate and independent scientific
research that has concluded that natural stone is perfectly safe to
use in homes. The report was prompted by a group
that claims to be independent, but is actually funded by two
companies that manufacture synthetic stone counters made of quartz
gravel, resins, coloring agents and other chemicals. To learn about facts please visit http://www.marble-institute.com/industryresources/granite_radoninfo.cfm. "A considerable amount of research has been published in peer-reviewed scientific literature and all of it comes to the same conclusion: the levels of radon coming off a granite countertop are not excessive and not showing any risk for the population in their homes. To properly measure radon, one must calculate the emission rate in connection with the volume of air in the home. Much like paint fumes do, radon generally dilutes harmlessly into a home's air. To get even close to the type of dangerous levels of radon exposure that's been reported in news articles recently, a consumer would have to completely seal off the room, stay in that room 24/7 - for 72 years." - Dr. John McCarthy President, Environmental Health & Engineering
