Radon at 3.5 pCi/L
Derrick Smith went up 40 feet to the roof of the house and fed the 4 inch
plastic radon tube down the chimney and they connected it to the pipe
in the fireplace. The job is now complete. We will see if this helps.
I will leave the monitor in place for awhile to see if there is a positive
effect. If not we will place a plastic curtain against the basement wall
and put the monitor inside to check for radon permeating the basement
walls. More work was done in the NE parlor and it is essentially finished
with the last finish coat on and smoothed.
