Transmission Factor Effects on the Average Forward Range of Compton Electrons.

Abstract

Compton electrons generated in air by gamma rays produced by nuclear explosions are known to cause transient electromagnetic fields called the electromagnetic pulse (EMP) or radioflash. The average forward range of the Compton electrons in air is a principal factor governing the strength of the EMP. Previous estimates of the average forward range of Compton electrons were based on an energy-independent electron transmission factor. This investigation uses an energy-independent electron transmission factor to obtain more accurate results. Results from the two methods are in agreement for an incident gamma energy of 1.5 MeV, and disagree by 7 and 10 percent for incident gamma energies of 0.3 and 10.0 MeV, respectively. Simple numerical fits to the new results are included. (Author)
