Radioactive kitchen counters are a modern feature to irradiate your food at home.  :-)JROn Jul 25, 2008, at 9:00 PM, Rodney wrote:Hi folks:This may have some relevance:"  The Environmental Protection Agency explains on its Web site that: "The presence of radon in your home can pose a danger to your family's health.

Thanks Rodney,

It might be 2 diff things.

The home that CONTAINS 4 pCi/L may be a lot higher than the sample radiating

4 pCi/L.

That piece might have to radiate a year to fill the home.

Hi folks:

This may have some relevance:

" The Environmental Protection Agency explains on its Web site that: " The

presence of radon in your home can pose a danger to your family's health. It

is the leading cause of lung cancer among non-smokers, the second-leading

cause of lung cancer in America, and claims about 20,000 lives annually. " "

" The amount of radon in the air is measured in " picoCuries per liter of

air, " or " pCi/L, " and the EPA says 4 pCi/L is the level of radon exposure

that requires someone to take action. The agency also says levels lower than

that " still pose a risk " . "

" On The Early Show Friday, Stanley Liebert, quality assurance director at

CMT Laboratories in Clifton Park, N.Y. showed co-anchor Harry a chunk

of granite countertop emitting 4.4 pCi/L and said, " The probability is we're

looking at a problem here. " "

So, if the above is accurate, the issue seems to be that some granite has

surprisingly high levels of uranium/radon, and others negligible amounts.

You may have to test the individual sample/kitchen to know which.
