airborne releases from area sources

[William McCabe <WMCCABE@tnrcc.state.tx.us>]

Does anybody have any information or references regarding at what
distance from an area source (e.g., acres of contaminated ground
surface) could one treat calculation of airborne releases as if they were
coming from a point source?   Would such a calculation be proper or
appropriate?  Any help or information would be appreciated.

Thanks in advance.
