Hey guys,I don't have an agenda here. I don't know how the stone is processed and radon comes from decaying Uranium and has a very long half life. I have done many radon tests and have never had a zero reading. Radon is everywhere in varying degrees, and is the second leading cause of lung cancer, if you check with the Amertican Cancer Society.If there is radon in a material, airing it out will not get rid of the radon, it will continue to off gas. Radon is not an issue on the exterior of the house because it is not in a confined area. I am not looking for a fight just some factual answers.
The whole radon test for homeowners is a big scam. Better tell the miners who spend more countless hours underground that they are more susceptible to radon, etc, than a typical homeowner. I look at radon tests as an unneeded expense, next to some of the other snake oil that is being sold out there.
Dick, I just looked up the whois on this so called website that was listed, and it comes up listed with namecheap as the domain name provider. I do have to love the "About Us" that the site that was linked has. All the OP linked was someone's blog that has been or has not been active since 2007.
