What would the fun in telling you? Like you're gonna walk on a rake and shoot each of your balls in opposite directions and the tip of your dingus up towards your chin, not gonna tell you when that's gonna happen either.
Zone 1 here. Did the testing and was twice the EPA recommended level. Put in a system which brought it down to next to nothing. Apparently it's one of the highest factors towards lung cancer - behind smoking.
Yes because organic material doesn’t break down and create/transform into soil over many years. And other materials don’t break down over millions of years and change state. But I’m sure you should start spending all of your free time and sleeping in your basement.
It won't change on an atomic level, goober. Actually, that is incorrect... carbon14 will decay into carbon12 over time, but I can't think of a single nuclide that would be considered "organic" that will decay into radon.
funny thing... in new SFH construction it probably could have prevented radon intrusion by the use of 10 mill poly and a lil quality control of the plumbing penetrations. Net cost maybe $400 all in. Which Im sure youre system cost 5x that.
I put in a mitigation fan when we built this place, It was really inexpensive to add the ground pipe before the basement slab was poured and worth the ease of mind.
About $1k but I don't have a huge footprint. House is about 60 years old so I'll give them the benefit of the doubt on this one
