Thanks for posting. Radon is on my list of things I need to check. I keep forgetting about it.
Before spending money on a radon test, check the maps. A lot of people live is areas with little to know radon danger.
I dealt with it a lot when I was in real estate. It’s like playing darts in the dark. I read that the reason the govt decided to worry about radon was that 20,000 people a year die of lung cancer who didn’t smoke and they don’t know why. So, they blamed radon. After decades of radon mitigation, I don’t think the number has changed. USA standard is 7 PPH, Canada is 10. Why the difference? Because at 7 most of Canada wouldn’t be habitable. Maybe some Canada peeps can reveal more or correct me, that was the talk at the time. If you don’t have a basement, it’s not very relevant in my opinion. That’s where the high readings come from. Wells are the most common source of the really bad readings, I’ve seen high 30’s. Comes right through your shower and into your face. Was not an issue for over 100 years. You can read 2 pch anywhere. 4 walls, you go to four. Seven is death, 6 is fine. Based on what? Nothing.
My parents grew up with coal furnaces being used in their houses, said it was the best heater ever they said, both lived into their 80's.
Good point
