Abstract:

A complete graphical presentation is given of an Oak Ridge transport calculation of the nuclear environment at the air-earth interface generated by point sources of monoenergetic neutrons. Monte Carlo methods were employed in the calculations computer codes, 05R and OGRE. The graphs contain the time, energy, angular and spatial distributions of the gamma rays and neutrons from each of 8 monoenergetic sources ranging from 0.1 to 15 MeV. The calculations extend out to 1375 m from the source. The graphical form is suitable for synthesizing the environment from a source of nuclear weapon neutrons of any spectral distribution. Only neutrons with energies above 0.1 MeV are considered in this portions of the calculation. Thermal neutrons and the gamma rays resulting from their capture are included in the graphs of a discrete ordinate transport calculation computer code DOT to appear in further volumes under this same title. The attending secondary gamma ray environments are presented. Author
