Radon in Granite Countertops

Has anyone ever heard of dangerous amounts of Radon in some Granite counter tops? I have been in the trades for years and this is new to me. Any unbiased help would be appreciated as I have a lot of Granite in my new home.

Radon is a radioactive gas formed by the decay of uranium.

Unless you have high amounts of uranium contained in the granite counter tops it shouldn't be a concern.

Now if the counter tops glow at night then maybe there's an issue.:)

OH OH I did some honey onyx tops with under counter lighting, so that when they had dinner parties it would give off a golden colored glow. hope they don't think they are being radiated.

no worries of radon. most negative publicity comes either from not truly understanding how something happens or from competing products.

Nothing like a nice solid granite countertop with Cherynobyl inserts ... :p:D

Actually, most urainium deposits were formed when the radioactive elements leached out of granite. Granite almost always has uranium elements, some more than others, as much as 7,000 times more in some cases. High sensitivity airborne gamma-ray spectrometry has been used since the mid-1970’s in support of geological mapping and mineral exploration

This study did a good job on explaining the risks.

Only one sample (Azoles Bahia) failed the sample, but the conclusions were eye opening. They recomended envioromental monitoring where granite mateials are used inside homes or anyplace that people had direct access to the material. The studies authors also warn of serious economic and social issues if the stone industry doesn't stop the practice of using different names for the same stone, as a simple mistake could result in a high radiation content granite being used inside a home.

Other studies have show as many as 25% of the tested samples failing to meet UN standards. Not safe standards, but UN standards. There is no safe level of radiation.

This site is a bit over the top, but their science is valid.

The info on the Chinese granites was interesting.

I'd get the granite tested if I were you to make sure it is one of the safer granites. There are plenty of them available.

" UN Standards " ? As in " United Nations " ?
