This paper presents a new method by which the density of radon in ground water could be continuously and automatically measured on the basis of Gas-Water phase equilibrium principle of radon. In the paper the author deduces the mathematics expression for the method, discusses its sensibility and time response etc., and compares the theory with experimental results attained by water-radon measuring apparatus based on this principle. The results show that this new method can meet with the requirments of observation of radon in earthquake prediction and geological circles.
