First thing this morning I have a stop in Pullman to set up radon re-test - follow-up radon testing as recommended by the EPA. The first test gave us a result right at the action level of 4.0 pCu/L and we want to make sure that we have a good number. Since the testing is done by sampling, a small statistical bias can enter into the results, hence the retest fro radon gas.
We're also running a longer test which will give us a smoother data set.
And, since I always offer a free radon follow-up test if the clients wants it, this test is free.
