Abstract: Puffs of the inert gas 85Kr were released at the surface level and were permitted to drift through a three-dimensional grid of Geiger counter sensors extending to a height of 21 m and to a distance of 800 M. Concentrations ...

Abstract: Analysis of a series of 31 field diffusion experiments permitted direct specification of the benefit of increased stack height. In the experiments, two tracers were released simultaneously from two different elevations on ...

Abstract: A brief description is given of the Hanford inert gas tracer system employed in atmospheric diffusion studies. Among the advantages of the system are the detailed histories of concentration generated simultaneously at 64 ...

Abstract: The behavior of the quantity S = σy/xσ? for surface releases of tracers is examined. Variations in this quantity for different field programs are shown to be attributable largely to variations in sampling time t and averaging ...
