You should expect to pay roughly $1k to have a professional drill a hole in your basement floor and run a PVC pipe up to the attic (bonus points if your builder had the foresight to build the pipe into the wall) and install a fan that exhausts out the roof, or run the pipe up the exterior of the house with the fan outside. 4.6 should be extremely easy to take care of; mine was in the mid-20s and dropped to <1piC/L after the fan was installed.
I'd see if you can get radon remediation in your contract, as this could be considered a health/safety issue.
If you're handy, you can do this yourself. Family Handyman had a good article on it. Just remember to follow the proper procedures.
We've requested the radon as well as a few other minor issues be remediated before we close, or at the very least have them knock the price of the repairs off the total home price and we an get it completed on our own. I just really don't want to pay for it.
This is a finished basement that will have a secondary living room as well as the master bedroom for my wife and I.Maybe you could live with 4.6pCi/L for now if they won't remediate since it's so close to the EPA-level. You've gotta keep in mind that the reading was taken in your basement - how much of that is actually getting through to the first floor, and is this a finished basement you'll be spending a lot of time in? I know when my multiple-day testing was being performed with the fancy machine, simply opening the basement door to get to the garage was enough to drop the readings down from 25pCi/L to 18pCi/L. You might want to look into passive systems and see if they're any good.
We had a radon test done at our current house before we bought it. The test took a couple of days and it looked like someone tried to tamper with the results. The inspector who did the test was taking temperature readings along with the radon readings and there were huge drops in the house temps and radon levels during the testing period. It was winter and someone was obviously opening windows trying to air the place out. The inspector went back to the seller with his concerns and they quickly consented to pay for the mitigation. I want to say it was around $5k. We had the exhaust put in and our whole crawl spaced sealed with plastic.
What was the cost if you don't mind my asking?Shouldn't be a problem to get the sellers to cover this, pretty standard practice in my area. Radon is ubiquitous here in Eastern PA. My house had a level of 68 before remediation. Sellers took care of it before close and I have had a meter running down in the basement since, never breaks 1 now.
The house already had a ventilation pipe running under the slab and through the wall into the attic and exhausting outside through the rough, so all that was done is that a motor was installed in the attic to actively move air. Cost around 900 I think, to do the whole thing would have likely been 1500ish or at least that's what I've had friends pay.What was the cost if you don't mind my asking?

Im wondering if the PVC that use already in use to vent the furnace can be piggy backed on or if it has to go roof level.
The cut off is much higher than safe.I have a meter that runs 24/7 and it's 5.0 picocuries per liter. I figure that's close enough to the cut off that I'm not going to worry about it.
But the problem is the sump pump hole. That's where it's probably coming in. And just keeping the basement door open dropped it from 6.1 to 5.
My pipe has a vacuum gauge with a warning message to call a number if the pressure changes beyond a certain point. That kind of makes me think it shouldn't be shared with any other vents.
Radon is such a fucking scam...
Since I work in a related field I was aware of the significant disinformation around Radon back in 1995. The best recent summary I have found is this one.
Are you sure this isn’t radiation lobbyist propaganda.
Honestly, since I understand statistics, I would be moved by a frew good google scholar citations.
so the finding is every 1.6 pl = a 30% increase in chances of lung cancer and smoking is multiplicative not additive.It is really hard to find good data. The one that got me really going down the path was this one. No one really had anything to counter this for a very long time. Eventually there was a very limited study out of Iowa that showed some evidence to the contrary. There was a pretty good study out of Sweden that had some reasonable controls. I would point you to the table at the end that compares smokers risk vs non smokers.
