With the legion of both deniers and alarmists out there attempting to monopolize the discussion over the safety of granite countertops, it is difficult to find unbiased information.  Peruse the comments in the above post and you can see the discussion has devolved into name calling.  The deniers, many of whom work in the granite industry, blast any insinuation that granite could be dangerous as “fear-mongering” and put down the current research as “junk science.”  The alarmists, many of whom sell competing countertops, argue that consumers shouldn’t take the risk that comes with granite.  The truth, as with most heated arguments, can be found somewhere in the middle.

Please visit an updated post on radon in granite countertops here:  A Rational Discussion on Radon in Granite Countertops

The Marble Institute of America better get ready for another round of fighting because the issue of radon in granite countertops is back. For the past decade, the MIA has been trying, with much success, to squash the rumor that granite countertops have the potential to add dangerous amounts of radon in the home. A new study being conducted by Houston area not-for-profit BuildClean is raising old fears about the dangers of granite countertops, and its preliminary results show that while most granite countertops in the study contain very little to no radon at all, the countertops that do contain radon have levels that are frighteningly high. While consumers can be secure in the fact that the vast majority of granite is perfectly safe, a small percentage is still in question, and no independent scientific study exists to assuage consumer fears.

The first issue of Solid Surface in 1995 explored the possibility that granite countertops may pose a health risk. Soon, the MIA issued their response, which attacked the credibility of the science involved in the study as well as the fact that the advertisers in the journal included companies that competed with granite countertop manufacturers. But one phrase in the response, a highlighted phrase no less, is troubling: “…actual levels of radon gas emmissions are so low as to be insignificant and generally represent no threat.” As a father, I don’t want to be assured that there is “generally” no threat to my family. I want to know there is no threat. And after BuildClean* found that 3 of 95 granite countertops contained harmful amounts of radon, would the MIA consider such a small number to be “generally” no threat? I’m sure the owners of those three countertops are not reassured.
