The effects of air and ground Composition perturbations upon energy deposition rates and compton electron currents from a surface burst. Final report, 17 November 1976-10 November 1978
A series of time-dependent Monte Carlo perturbation calculations has been performed to determine, as functions of neutron source energy band, the energy deposition rates and Compton electron sources in the air due to neutron and secondary photon interactions from weapons at a one meter height of burst. Both total value and composition perturbation differences were calculated for atmospheric water volume fractions of 2% and 4%. Nevada test soil was used for the base case ground composition. The small perturbations considered were water in air and water, silicon, aluminum and iron in ground. The energy deposition rates and Compton electron sources were determined as functions of time (out to 100-ms local time), in 49 radial and altitude scoring bins surrounding the four isotropic point sources. Answers were obtained for penetrations from 0 to 2.4 km in the horizontal direction and from 0 to 1.5 km above the air-ground interface. The raw data have been stored on tapes at HDL. Some sample results are presented and described in this report. More analysis is required to obtain further results.
