It's interesting that the radon concentration after 3 and 4 weeks of treatment is higher than the concentration after 2 weeks of treatment.

Negative concentration? That blows my mind!

Yeah, the same trend showed up in our data...the amount of pollutant actually increased, then decreased, then increased again on the final point.
Also, the negative concentration was probably derived from a model or regression of some kind. Who wants to sit around for six months watching radon, water, and a sheet of nothing that's too thin to see anyway?
