Interesting article post in the New York Times on July 24 that shared with its readers the possibility of radiation being omitted from some granite counter tops- YES... RADIATION!!!
"SHORTLY before Lynn Sugarman of Teaneck, N.J., bought her summer home in Lake George, N.Y., two years ago, a routine inspection revealed it had elevated levels of radon, a radioactive gas that can cause lung cancer. So she called a radon measurement and mitigation technician to find the source.
Using devices like the Geiger counter and the radiation detection instrument Stanley Liebert measures the radiation and radon emanating from granite like that in Lynn Sugarman's kitchen counters.
"He went from room to room," said Dr. Sugarman, a pediatrician. But he stopped in his tracks in the kitchen, which had richly grained cream, brown and burgundy granite countertops. His Geiger counter indicated that the granite was emitting radiation at levels 10 times higher than those he had measured elsewhere in the house. The granite, it turned out, contained high levels of uranium, which is not only radioactive but releases radon gas as it decays. "The health risk to me and my family was probably small," Dr. Sugarman said, "but I felt it was an unnecessary risk.
It's not that all granite is dangerous," said Stanley Liebert, the quality assurance director at CMT Laboratories in Clifton Park, N.Y., who took radiation measurements at Dr. Sugarman's house. "But I've seen a few that might heat up your Cheerios a little."
