After a brief introduction to elementary neutron transport theory, the problem of the transmission of neutrons by straight and bent cylindrical ducts penetrating a radiation shield is considered. The direct scattered component is treated to a first approximation using the diffusion approximation applied to the distribution of effective anisotropic sources along the duct wall. The geometric approximations are such that the method is applicable mainly to ducts with diameter-to-length ratios small compared to unity.
