Gamma Attenuation by Asphalt

["Leo M. Lowe" <llowe@senes.on.ca>]

Hello all:

To supplement some calculations, we are looking for references/data on the
gamma attenuation ability of standard asphalt.   Direct measurement data,
particularly related to the natural thorium and uranium series, would be
specifically useful.

You may respond directly to the undersigned.  Thanks for your time.
