Researching Granite and Radon
We are thinking about replacing our Corian counters with granite. Want to avoid granite colors that regularly test high for radon emissions (Crema Bordeaux, Yellow Star, Niagara Gold for instance.) We were all excited about "Golden Fantasy" until we discovered that it has tested positive.
Is there any resource that keeps track of what granite colors test high, and which ones test at or near zero? We have not been able to find information about many of the colors we have looked at.
Thanks very much.
