More seriously, how about call your local health
department. If nothing else, they can send someone
out to study the matter. And then use the force of
government to make you do expensive things that
make the problem worse, at your own expense.

I've been trouble-shooting for 3 years my radon
problem...but just recently believe
the problem is outdoors and not indoors.

I have an electronic radon monitor that updates
reading like every 30 minutes...i've
had it as well for about 3 years.

Basically I've sealed everything a 100% indoors
for the most part... the foundation
was completely sealed of cracks... thick radon
plastic on top...and vinyl flooring on
top of that..

I realized when I had the windows closed for an
extended period of time, the radon
levels would eventually fall.. *(especially during
the winter when the ground is
frozen and there is snow everywhere...like it is
right now)

During the Spring, Summer, and Autumn...if I
opened the windows...the radon levels
would slowly increase in the house instead of
decrease.... I was pretty baffled by
this, so I put the entire electronic monitor
outdoors instead of indoors...and the
levels remained the same or even rose a bit.

This convinced me that the problem is outdoors and
not indoors... I live in the
Mountains *(Pennsylvania)

And over the 3 year period the numbers generally
averaged from 4.0 to
8.0...indoors... but never really got above 9.0 .
(currently , since the ground is
frozen...the indoor level is 1.9)

So my next question is...what to do now ? * I even
put the electronic radon monitor
outdoors on the 2nd deck *(elevated)..and the
number were about the same there as
well.

So in general, my outdoor radon levels average
around 4.0 to 6.0 for the most part...
(the 8.0 I mentioned above was an indoor reading
dooring the summer)

The house was built in 1992... I bought it in
2005.

any advice is appreciated

PA is known as an area with high radon levels. Have you tried the
meter in another town at least 10 miles away, and have you had the
meter calibrated as another poster recommended? It sounds like the
house is built on a slab. Is that correct?
