On Sep 29, 8:17=A0am, "Jack" asked about radon abatement, and immediately the conspiracy theorists came out to play...
Let's address some issues here.
(1) Radon in high enough concentrations is a legitimate concern, particularly for people with existing health issues and, apparently, pets. (Smaller animals, higher metabolism, higher risk.)
(2) Radon is found in higher concentrations in rockier soils, especially around mountainous or hilly areas with a high presence of granite (the source of much radon leaching).
(3) The reason we didn't hear about radon years ago or in older houses is because it builds up in areas not properly ventilated. Old houses were leakier; new houses tend to be more air-tight to conserve on energy usage.
(4) You're going to see more houses testing positive for elevated levels of radon as we have a higher percentage of foreclosures - empty houses - sitting on the market for months. People aren't going in and out as much (less air exchange with outside), and the HVAC isn't running as often to "stir up" the air.
Do NOT make a hyperbolic claim about radon abatement being a scam. I know of a couple in Colorado whose house tested for something like 120 pCi/L (picocuries per liter) which is 30x the maximum acceptable level according to the EPA. THAT needs abatement.
Did my own house, which tested at 12-13 pCi/L after sitting, foreclosed, for 6-1/2 months need to be abated before we moved in? Probably not, but we had it done anyway because one of our cats has allergies and asthma and my immune system makes me susceptible so why take the risk if we were getting a credit for it at settlement?
My one dislike is the noise of the air exiting the pipe on the roof. We vented it out through the basement wall into the garage and then through the garage roof. The part of our deck where I have the grill is where the garage roof is ~4 feet above the deck, so you can hear the muted roar/rush of the fan venting the air. I'd like to crank the rheostat on the fan down to a slower speed to see if we can alleviate some of that white noise on the back deck...
But otherwise, I don't have any problem with the abatement.
