3pCi/L I whole heartedly agree but if you are asking because you are taking the home inspector's exam then the answer is 3WL. I know this because I answered 3WL as an experiment and got 100% on the test. I have never heard radon expressed as WL and can kind no information on it so it may not be the correct answer but it is for the Oklahoma home inspector's practice exam on NACHI website. I feel quite justified giving this information on the internet because radon testing is not part of the standards on inspection for Oklahoma any way so it shouldn't even be on the test.
