A model based on atmospheric gamma radiation from radon progeny adsorbed onto the surface of rain and snow was used to monitor the precipitation rates. The gamma ray rates observed were proportional to the 0.45 power for rain, but for snow a linear relationship was observed. Correlation coefficients ranging from 0.85 to 0.95 and improving with elevation were obtained when data were fit with predominantly surface adsorption model.
