radon levels under slab
 

I've been using a radon detector (National Safety Products Pro 3) to
check radon levels in our house. Levels are high, but within my
expectations for our situation (25 in basement, 15 upstairs).

But, then I put a hole in the cellar floor, dug out a 1' deep hole, and
put the detector down there. It's getting readings of 300+. I'm kind
of surprised at this If anyone has any insight on 'in ground' radon
measurements, I'd appreciate hearing.

(NB: It would be OK to spare me the 'OMG, evacuate the house and call a
HazMat team" comments. Bandwidth is a precious resource.)

TIA,
George

Doesn't surprise me that readings are very high in-ground.

Some insight he

Google around. You may be able to find maps of Radon levels
in your geographic area or state.

I used to live in Lancaster, PA. We had a radon problem in that area
of PA -- the "Reading Prong," I believe. The radon abatement mechanism
was to drill a couple of large holes in the cellar floor and pump out
the air under the slab. We got the reading down to somewhat less than
1 pC/L after a week, and could easily hold it there. They also caulked
up any cracks in the basement wall/floor.

In future, please abbreviate "bandwidth" as "bndwth," thereby saving
precious bndwth.
