Radon is a cancer-causing, radioactive gas that is emitted as uranium decays. As most rocks contain traces of uranium, this gas is present in the soil virtually everywhere on Earth. Like uranium, radon decays, too. If it does this in your lungs, the alpha particles it releases can harm the DNA in your cells.

“When we talk about radon risk, we really mean the risk from radon and its decay products,” said Phillip Price, a physicist at Lawrence Berkeley National Laboratory. If enough of your DNA is damaged, the mutations pile up and you can be dealing with a host of health problems, including lung cancer.

Radon is everywhere, but it doesn’t usually pose much of a risk because it disperses into the open air. “What’s unnatural are the radon levels that accumulate indoors,” says James McLaughlin, president of the European Radon Association.


For our clients who are buying a home, we offer peace of mind that your home is safe from a dangerously elevated level of radon gas, as well as potentially saving them nearly $1,200, which is the average cost of having a radon mitigation system installed.

When faced with the problem of elevated radon levels, the seller may pay to have a radon mitigation system installed. Finding out during the inspection contingency period is key. Once you have purchased the home, that responsibility is all yours.

Safety 1st Home Inspection only uses professional-quality continuous radon monitors that are calibrated annually. Contact us today to learn more about Radon testing and why it is so important if you are buying a home in Knoxville.
