NUCLEAR SHIELDING FOR SPACE ENVIRONMENT--THE SCATTERING SHIELD. Paper 15 of PAPERS FROM SEVENTH SEMIANNUAL SHIELDING INFORMATION MEETING, OCTOBER 14-15, 1959
Shielding of a nuclear reactor in a space vehicle should be designed to eliminate radiation, predominantly by scattering it into space rather than by absorption. This can eliminate much of the multiply scattered radiation (build- up) that would normally contribute to the dose. The following general rules for nuclear shadow shielding in space environment constitute what may be called the space scattering principles: (1) multiple splitting of the shadow shield to increase the probability of scattering into space; (2) shaping of each shadow disk to increase scattering into space; (3) reliance on good scatterers with more isotropic cross section; and (4) the possibility of using low density materials without weight penalty because of the one dimensional geometry. Some schematic calculation results are presented. (auth)
