摘要

Process for continuously and rapidly acquiring changes in concentration of radon gas dissolved in water comprises pumping new radon-free gas through a gas chamber surrounded by water and separated by a water-tight gas-permeable membrane into a radon measuring device; and continuously measuring. An Independent claim is also included for a device for continuously and rapidly acquiring changes in concentration of radon gas dissolved in water comprising a gas chamber having an inlet connected to a gas source and an outlet connected to the radon measuring device. Preferred Features: The radon-free gas is air. The gas is released to the environment after it leaves the radon measuring device. The water and the measuring gas are introduced counter-currently or in parallel to the membrane. The gas chamber is a diffusion tube.
