For those of you who don’t already know, the “scare tactics” regarding granite and radon are out there once again. Basically, it’s the same old re-run from years ago: “Are granite countertops killing innocent families? We don’t know, but we’re looking into it. In the meantime, why don’t you try this alternative material?” It’s not worth getting into who is behind the latest version of this nonsense anymore, but let’s just say that there are some deep pockets involved. Moreover, the spread of misinformation is costing the stone industry a significant amount of money. Shortly after this latest smear campaign against granite, the Marble Institute of America (MIA) funded an independent study that — once again — concluded that granite is safe to use in kitchens. The study, designed to determine whether radon gas sometimes released by natural stone poses any health risk, was conducted by an independent geochemistry researcher. Included in this study were 13 of the most popular types of granites used in countertop applications, representing up to 85% of the granite countertops sold in the U.S. They include: New Venetian Gold, which is imported from Brazil. It is a medium-grained, yellow-beige gneiss with many dark red garnets. Ubatuba, also imported from Brazil. It is a medium- to coarse-grained, olive-green granite. Santa Cecilia, from Brazil. It is a coarse-grained, yellow-grey gneiss with up to pie-sized, red garnets. Tropic Brown, from Saudi Arabia. It is a medium-grained, brown granite. Absolute Black, from India. It is black basalt. Tan Brown, from India. It is a black-brown igneous rock with big, shapeless, brown-red feldspar crystals. Giallo Ornamental, from Brazil. It is a coarse-grained, brown-yellow granulite with some brown-red garnets. Crema Bordeaux, from Brazil. It is also known as Juparana Crema Bordeaux, an exceptionally coarse material that is commercially sold as granite, even though it is not geologically a granite. Baltic Brown, from Finland. It is a brown-black granite. Giallo Veneziano, from Brazil. It is a medium- to coarse-grained, ochre-yellow to golden-brown, also light pink, gneiss. Dakota Mahogany, from the U.S. It is a medium- to coarse-grained, brown-red granite. China Black, from China. It is a fine-grained basalt. Yellow Star, from China. It is a medium-grained yellow to pink granite. The results found that Crema Bordeaux, which emitted the greatest amount of radon, contributes less than 7% of the EPA's standard for action. The stone emitted 0.27 pCi/L, or less than 7% of the EPA's level of 4.0 pCi/L, well below any cause for health concerns. Tropic Brown and Baltic Brown, second and third in radon emanation amounted to only 1% of the standard for action. The other granites added almost immeasurable amounts of radon to the house. Tests were designed to measure the amount of radon each granite type added to the interior of a 2,000-square-foot home with 8-foot ceilings. However, the study did not reflect the ventilation normally found in a typical home, through windows, vents, heating and air conditioning. A typical heating, ventilation, air-conditioning system can exchange a home's air up to six times per hour. This natural ventilation would dissipate radon gas levels significantly. "Because the study does not reflect the natural ventilation typically found in homes, real-world radon concentrations are likely to be even lower than those measured in the study. The misinformation campaign is being driven through front groups that purport to be consumer advocates, but are merely trying to create consumer fears about natural stone. The intention of this article is to fight the unfounded fear mongering to reassure the public. The MIA has already invested $50,000 from the Truth About Granite Fund to stem attempts to scare consumers about granite, and that amount could increase dramatically by year’s end. It is important that we have all the legal, technical, public relations and marketing/advertising tools we need to protect the good name of granite and to reassure consumers that granite is as safe as it is beautiful, durable and practical. The Truth About Granite Fund will be a special segregated account whose expenditures will be overseen by the MIA executive committee. Contributions to the fund should be sent to Marble Institute of America/Truth About Granite Fund at 28901 Clemens Rd, Suite 100, Westlake, OH 44145. -Adam Lahley -Check back regularly for new info, or go to www.austin-tile.com
