Book Description
Results are presented of experiments carried out with an 11 x 11-inch duct in concrete with one right-angle bend, using Co]x60 as a gamma-ray source. An empirical expression is obtained which adequately represents most of the experimental results of measurements available at the present time.

Book Description
The use of the albedo approach for the analytical prediction of attenuation characteristics of two-legged rectangluar ducts transmitting gamma rays is extended to cases involving the asymmetrical location of source and/or detector. Illustrative problems are presented and solved.

Book Description
An analytical approach is developed to permit determination of gamma radiation attenuation as it passes through two-legged rectangular ducts and shelter entranceways. The approach used employs the albedo concept for wall scattering and included correction terms necessary to account for the "corner lip effect." With appropriate simplifying assumptions, moderately simple engineering formulas are obtained. Actual use of the formulas requires better knowledge of differential angular albedo than is presently available; however, by assuming isotropic distribution of the albedo function, a very good comparison of experimental information with results calculated by this technique is obtained.
