Abstract
A series of tests designed to evaluate the attenuation introduced by a vertical wall adjacent to a horizontal field of contamination is described. The variation of the resultant attenuation with height is found to agree well with theory. Actual attenuation values measured are higher than those theoretically predicted by an amount equivalent to approximately eight percent of the wall thickness.
