Abstract

We study the doses generated by instantaneously released dense gas clouds. The dose is of practical importance since it is widely used as a measure of the harmful effect of an exposure. We take the doses from wind-tunnel experimental data. We extend from Davies' (1992) work to show that for later times after release the dose across repeat experiments may be fitted with a lognormal distribution. A simple box model is constructed from the dataset. It produces a reasonable model under some of the experimental conditions. We show how to use the repeats of experiments to produce a representative model.
