TRANSMISSION MATRIX AND MONTE CARLO GAMMA RAY PENETRATION. Final Report
Technical Report
·
OSTI ID:4277389
Two Monte Carlo gamma ray penetration codes, one for plane and one for spherical geometries, are presented. Important histories and how to estimate their importance, according to position within the shield, are described qualitatively. Test results for the Monte Carlo buildup factors are listed. A transmission matrix method of computing transmission through infinite plane parallel shields, made up of several layers, is presented. The matrix for a multilayer shield is the product of the matrices for the component layers. Variational principles for the multiple scattering theory of penetration through slabs are discussed. A procedure, which is adequate in a great many circumstances, to compute crudely the dose from gamma rays produced by inelastic neutron scattering in the shield is described. (auth)
