Abstract:

The split scatter shield consists of multiple shield sections which are separated from each other. When this type of shield is used outside the atmosphere, radiation scattering in each section has a high probability of escaping the shield system without rescattering. Consequently, this shield has been proposed as a replacement for the normal shield unit construction for space applications. The split shield is compared with a unit shield of the same weight and material in a hypothetical problem situation by computing the radiation attenuation by each. The problem is computed using point and circular source geometries assuming the sources to emit gamma rays only. The calculations are performed using simplifying assumptions so that computer programs are not necessary. A geometrical parameter study is performed for the split shield to determine the optimum number of sections, the optimum separation distance between sections, and the maximum flux attenuation. The results indicate that a split shield is capable of greater flux attenuation by a factor of more than four than a unit shield of the same weight. Author
