We moved into our home 17 years ago and had it tested right away as we know radon is a big problem in Iowa. We lived in several OLD homes before that had “cellar” so we hardly ever went down there. With this new home it had a finished basement that would be our family room. The testing revealed very high levels of radon so we installed the mitigation system. Others are suggesting you can do it yourself, which I guess its true, but again how much value do you place on your health. Also with the professional instal, we got a warranty so they came and replaced the fan motor after 10 years when it go very noisy.
On a related note my wife has gotten lung cancer twice in the past 7 years. Never around smokers in any way and when talking to the drs she said that she grew up living in a basement for a few years while her father built the up levels of her house. Also she spent lots of time in that basement. They all said that the radon she took in in that time, plus just the radon in our old houses most likely contributed to her cancer. So …… don’t mess around and NO I DONT THINK IT WAS A HOAX.
