We did a radon test on our house and found it to be elevated to 6. We were
told that it should have read 4.
It is a big deal to correct this problem. We live in Central New Jersey
Look at the Building Science Corporation web site.
They have a diagram of their suggested solution.
Since you haven't told us anything about the way your house is
there is no way we can tell you if it is " a big deal " or not.
I've looked at a lot of houses with radon systems installed, abd there
is usually a way to do it that's not too invasive.
Get an estimate from a remediator, and they should come up with an
estimate of $1000-$2500. The system is usually a 6-8 inch PVC pipe
stuck through a hole punched into the middle of the basement slab,
there's a motor and fan in the pipe, and the pipe exhausts somewhere
outside the house (in a specific fashion, at a specific location).
I'm not sure if there are kits avail. to the 'public' for doing this,
if you're of a mind to try it yourself. The only real not-off-the-shelf
item is the fan-motor assembly, and the little manometer that tells you
its actually working.
The good thing about having enough radon that you need to install a
system, is that after you install it, you'll have far less radon than
someone who didn't need the system. Properly installed, the systems are
A downside to doing it yourself is that you can't rtefer a future buyer
of your house to the installing company. Some people are very skittish
about a house that has a system.
You are at the borderline for the EPA radon exposure standard. But many
feel that standard is set at a ridiculously low level. In other words
it's more a product of bureaucratic rectal extrapolation than real
science. Dr. Geno Saccomanno did extensive research on Radon exposure in
Uranium mines and he found that levels as high as 20 pCi/l have no
measurable effects unless the people exposed are heavy smokers.
Fixing the problem usually runs $2500 for a slab vacuum fan and ducts.
If it were me, I'd continue to monitor the levels, but I wouldn't bother
doing anything unless they increased dramatically.
