Ceiling-shine is that radiation which enters through the wall of a structure, reflects from the ceiling and increases the radiation within a shielded space. In most cases the ceiling-shine contribution is small when compared to direct and wall-scattered radiation. In some cases it can be an important contribution. The present method of analyzing buildings, the Engineering Manual, OCD PM 100-1, includes the ceiling-shine effect in the air scattered contribution, but does not provide a separate method of analysis. This report discusses the theory and application of ceiling-shine and proposes a method of computing its contribution.
