Abstract

Concentrations of radon daughters in falling rain have been used to derive precipitation scavenging rates of those particles with which radon daughters are associated; presumably these are the particulate component of natural, background aerosol. Scavenging rates ranging from 10−4 to 10−3 s−1 are deduced from a comparison of the observations with the predictions of simple models of in-cloud scavenging processes.
