Abstract:

A series of curves is presented showing the scattered and direct neutron flux per initial neutron from a burst height of 50,000 feet and sampling altitudes from 30,000 to 100,000 feet. The data for these curves were calculated from a Monte Carlo Code. CONCLUSIONS The data for the 50,000foot burst height indicate that in the majority of cases, the greatest contributor to the total scattered neutron flux at the receiver is the lower sampling energy band. Generally, the total scattered neutron flux from the 14, 10, 5, and 2 Mev neutrons are fairly close at the same sampling altitude. More specifically, the flux from the lower energy neutrons is slightly higher than the flux from the higher energy neutrons at distances close in to the burst point. The opposite is true at distances farther out from the burst point. Author
