The highest I have recorded is a 21.4, but that was low compared to the client's neighbor who had a 27.8. The neighbor's wife was a non-smoker and otherwise in good health. Then she came down with lung cancer. That is what ended up prompting the radon testing for the neighbor who shared the findings with others in the neighborhood.

A broker friend of mine actually convinced me to finally do radon testing her friend was in there house for years and got lung cancer and went and did a radon test and came back a 28. Scary what's out there.

Highest Radon ???? 482 pCi/l FOR REAL !!!!!
See attached report. It was a house with deep water well in area with exposed soil in the basement. (pulling lots of soil gas as a chimney would) The area is has shale gas wells (uranium source....daughters of uranium are radium and then radon)

I was concerned that there was something else I was missing so the test was done again..... less than 5% difference.

In our area we have a 58% failure rate.....Thank you Marcellus Shale deposit. It is common to have between 20 and 30 pCi/l
The house we raised our family in had a reading of 85 pCi/l before radon system

Now for the good part...I will attach an article I wrote on Radon and the need for testing. Feel free to use it and share it.
I sold a lot of radon tests with that article ............... you can too !!!!!

Fantastic topic!

We had a radon test come back at 118 last year!!! It was a half basement/crawl space with dirt floor. Pretty much a mitigation nightmare.

We performed the retest post mitigation and the house was brought down to close to zero.

I’d say on average we’re between 2-12 pCi/L. Once or twice a month we’ll see a reading over 20 pCi/L.

Like I posted above, we’ve seen some pretty high readings!
