Abstract:

The results are described of an analysis of simultaneous measurements of radon concentration in the surface boundary layer of the atmosphere low-temperature radon-concentration determination using liquid nitrogen and the activated carbon-absorption method and in the soil, the amount of radon exhaled from the surface, and the coefficient of vertical turbulent mixing. Two series of measurements were made -- one 7 km south of Kirov in the summer of 1950 mainly under convective conditions, and the second in the Moscow region in the summer of 1962 with a surface boundary layer inversion. The effect of vertical turbulent mixing on the concentration of radon in the surface boundary layer was determined to be of major significance. Author
