The Validity of the Use of the Neutron Reduction Factor in Assessing Displacement Damage to Electronics in Armoured Vehicles

Abstract

The degree of protection from neutron irradiation afforded to electronics by armoured vehicles is most currently defined by the outside-to- inside ratio of the 1 MeV equivalent neutron fluence for Silicon. It has been proposed that this factor may be approximated by an experimentally measurable parameter - the neutron (tissue kerma) reduction factor. This report examines the validity of this assumption for a variety of realistic nuclear battlefield scenarios, calculated using the computer code VPF2. In addition the response of two neutron dosimeters in the calculated fields is examined. Keywords: Neutron; Nuclear radiation; Radiation protection; Silicon displacement damage; Radiation transport; Computer codes; Nuclear weapons.
