Those shiny granite countertops in your kitchen may be emitting harmful radiation, as well as radon, a radioactive gas.
Yes, you read that correctly. According to a piece in today's New York Times, "there have been…reports of 'hot' or potentially hazardous countertops" in recent years. Granite countertops have become extremely popular in homes across the country.
Now, before you grab your sledgehammer, it needs to be pointed out that not all granite emits nasty, invisible, and difficult to detect radiation. (Anyone seeing why this is freaking me out a little bit?) The Times says that "the more exotic and striated varieties from Brazil and Namibia" are more likely to contain the bad stuff than other types of stone.
Then again, who knows? The Environmental Protection Agency (EPA) says that radon gas levels higher than "4 picocuries per liter of air" is potentially hazardous – "about the same risk for cancer as smoking a half a pack of cigarettes per day." HALF A PACK PER DAY. (Sorry, but like I said, this freaks me out more than stories like this usually do.) One former granite-kitchened individual in the article had readings of "100 picocuries per liter". So that would be, what, 250 cigarettes per day? (Math isn't my strong suit; sorry if that's incorrect.) And Lou Witt from the EPA is quoted in the Times as saying, "There is no known safe level of radon or radiation…any exposure increases your health risk."
What to do? The article says that you can hire a tester from the American Association of Radon Scientists and Technologists. If you want to test for radon yourself (note that this doesn't test for radiation) you can visit http://epa.gov/radon or http://epa.gov/iaq/whereyoulive.html. Something tells me that the testers may get a few calls after people read today's Times.
