Subject: [USMA:46611] Can it get any harder?
I've been investigating the problem of radon buildup in homes in our
area. We live in a karstic limestone region in the Eastern Highland
Rim of the Nashville basin, just at the western edge of the
Cumberland Plateau. Our county seat, Spencer, is on the plateau and
located 7 km SE of our home. We have a basement, so this is more
than idle curiosity.
The State of Tennessee provides free testing (as does the National
Safety Council. The stated level of radon activity at or above which
action is recommended is 4 pCi/L or 0.02 WL.
Now, I understand curies and the radioactivity of radon. It's too
bad that the EPA and other federal and state agencies haven't
shifted to using becquerels yet, but that's another matter. But what
about "0.02 WL"?
Dear Jim and John,
Sorry, but I can't help myself:
Oh how our minds we do pervert,
When first we practice to convert.
Cheers,
