Recent Re-Measurement of the Neutron and Gamma-Ray Fields at Large Distances from a Prompt Critical Facility

Abstract

Over the past few years the neutron (and to a lesser extent gamma- ray) energy spectra at the NATO standard reference point (400m from the core) at the Aberdeen Pulsed Radiation Facility, Aberdeen Proving Ground, MD, US has been the subject of experimental and theoretical controversy. This report describes the Canadian results of a joint NATO spectroscopic and dosimetric program carried out to end the controversy. Free-field and in-vehicle spectra are given, along with free-field and phantom dosimetric results. As a result of this work, several benchmark results have now been obtained, and specific recommendations for future research are given. Keywords: Neutron, Gamma ray, Radiation spectroscopy, Anthropomorphic phantom, Radiation transport, Canada.
