Snow and Rain Washout Coefficients for Process Plant Radioiodine Vapour

Abstract

VERY little is known about the effectiveness of snow in scrubbing the atmosphere, and in the past there have been no reported measurements of the efficiencies with which atmospheric constituents are removed by snow. Theoretical calculations of the collection by raindrops of soluble gases have been reported by Chamberlain1; however, similar calculations for snow would require a knowledge of the electrostatic capacitance of the snow crystals and their number per unit volume in air.
