Abstract

Relative study of the gravimetric, optical and beta-absorption techniques has been made for the study of atmospheric particulate concentrations. C14 and Pm147 have been used as beta sources and it is found that for normal atmospheric dust loads the Cu betas are preferable and for heavily dust laden atmospheres the Pm147 betas are useful for obtaining reliable results.

The results show that the atmosphere around Trombay is loaded with dust in excess of permissible limits and that the observed concentration follow a log-normal distribution and indicate both a seasonal as well as a diurnal variation.
