In my mom and dad's house the sewer clean-out pit is bare clay. I measured a high of 120Bq/m3 ( for picocuries divide by 37) ten feet away. Finished basement 1980s no HVAC. I covered the pit temporarily with rigid foam insulation board and cardboard now it's down to 52 long-term and 38 short-term. My Dad died of IPF a lung scarring disease and it can be caused by radon exposure. He was a smoker early in his life I read about how the smoke particles and radon combination make it even worse.
I had high humidity in my crawl space. When I closed the vents I checked radon levels (after my former boss got lung cancer) The levels were high as our house is on rock. Had a Radon guy come in who sealed my crawlspace and installed a special pipe under the plastic then with a fan he vented it above my roofline. My Radon level now is 0.51 Pc/L I think it was 40 Pc/L before
I think there's a lot of factors in that. Running your furnace circulates the air more so it's less likely to have higher concentrations in the basement. Try measuring your radon level on the main floor. Just a guess but you probably have higher average levels in the cold season than warm season
It is really weird how contaminated soil could cause high levels of radon. Everyone thinks that this is BS, but it's not. As a nuclear scientist, this is the real deal. My friend's home turned out to have high levels of radon which was the direct result of having been built on a former land fill.
There are EPA maps for each state showing the average radon levels per county broken down into 3 Zones of potential radon levels. Just because you live in a certain zone does not directly indicate the radon levels of your house, it is completely dependent on the geology below your house combined with the negative pressure your house creates. Houses or apartments right next to each other can potentially have drastically different radon levels. Only way to know for sure is to test.
@@tonyzone8999 No idea, sorry. I try to pay cash for everything as it typically give the best price. In this case, they came down from $9300 to $8700. Worth it to me. The cheapest bid was just under 7K, but with cheaper material and not as good of a sealed installation. Hope this helps.
@@Atreid3s As I stated, I had lower bids, but I chose this one due to the higher thickness membrane, more thorough installation (sealing), and warranty. It’s worth my family’s health for a little more $, and it’s essentially capsulated now. We went from 8.0, to .0.3 in both crawl spaces. Money well spent.
How long do these radon mitigation systems last? Or when does the fan need replaced? Mine is 13 years old. The fan is noisy, but still seems to work. Got a quote years back for $500 to replace the fan.
Buy a new fan (should be roughly $100 - $150). You can probably buy the same model. You can easily replace the fan yourself because radon mitigation systems are installed with the expectation to replace the fan in the future.
@@eagles5769 try a passive system first (without fan); you can always add the fan later if passive is not effective. I installed just the pipe in my basement sump vented it out and the pressure differences between outside and inside of house were sufficient to drive radon levels from 17 picoCuries/L to less than 2.0.

Very good video thank you for the info

You kept saying 'basement' but radon exposure can still be an issue if you don't have a basement
I noticed during the warm season daily radon levels are higher in my basement than in the cold season
That makes sense. Most Gases are expansive
The norm is higher in the colder months. Cold outside air pushes down through the soil and the stack effect in the home pushes radon up into the home.

What if you have a single-story gone with no basement but an underground in-garage storm shelter?
Is this a larger issues in different locations? In the Northwest we barely hear about this
Yes. It is a regional thing.

I just had this put in our new house.
Two crawlspaces piped together. $8700 total.
Do they finance

Seems like you got ripped off. $8700 for drilling a couple holes and installing some pvc pipe?

@@Cravz69 what membrane?
So if I buy this kit will it save me from spending $160 for a professional raydon test?
I think you would still need to do the lab side as well.
$20 for the kit. I don't know what the charge is for the test itself.
@@robertrocheville7769 Thank you

@@robopaul9 Thank you. The person I spoke to made it sound like it was proprietary. I'll check it out.

Oh. Radon now. That’s good.
Wait a minute. What you are saying is the fix is causing more radon to come into basement.
It sucks the air from under the basement slab so before it can get into the basement.
it's the only 'youtube' you guys do in the house?(as he broadcasts on youtube) OK pal that's what you think lol

Still haven't fixed the title, huh?
He doesn't really understand geology or what is going on within the home. You missed the most important points!!
Contact me for better information.
hi. can you kindly advise what's missed? I'm living in a basement and trying to determine what the best course of action.... thanks!
