Time-Dependent Energy Deposition and Compton Electron Currents from Three Selected Low-Altitude Bursts.
Abstract
A series of time-dependent Monte Carlo calculations has been performed to determine the energy deposition rates and compton electron sources in air due to neutron and secondary photon interactions from low-altitude nuclear bursts. These calculations were made with a modified version of the SAM-CE computer program. Three point isotropic sources of primary neutron radiation were considered: a degraded fission weapon at a 50-meter height of burst (HOB), a degraded fission weapon at a 100-meter HOB, and a typical 14MeV source at a 100-meter HOB. The energy deposition rates and Compton electron sources were determined as functions of time, in 74 radial and altitude (R-Z) scoring bins surrounding the three assumed burst points. The atmosphere was taken to be homogeneous at an assumed density of 0.00111 g/cub cm. Answers were obtained for penetrations (in all directions in air) ranging from 0 to 2.4 kilometers which correspond to a penetration of 266.4 g/sq cm at the assumed air density. (Author)
