A comparison is made between experiment and theory for the calculation of shielding by a structure against fallout radiation. Experimental results for exposure penetrating a roof slab, and for reduction factor, are found to agree with moments theory calculations, often to better than 10 when the geometry factor L sub a omega, X was used. A comparison between experiment and theory may be inaccurate due to anisotropy of the experimental source, to lack of source reflection in roof experiments, and due to error in estimating the thickness of the roof. The magnitudes of the errors due to these effects are investigated, and found to be small, but not necessarily negligible. Detailed results of penetration in iron and concrete, due to plane isotropic sources of various energies are given, and a review of ground contribution to fallout radiation penetration through simple structures is appended.
