Radon-rich water revealed to air continuously sheds radon by volatilization due to the fact that atmospheric radon focus are really reduced. Therefore, ground water usually has higher focus of 222Rn than surface area water, because the radon is continuously created by contaminated decay of 226Ra present in rocks.
