Evaluation of Neutron Dose Measurement Techniques for Use in a Shipboard Environment

Abstract

Recently, the biological effect of fast neutrons has been under review. As a result, adjustments may be required in the current dose equivalence algorithms when fast neutron field are present. Since many Navy personnel are exposed routinely to fast neutron radiation fields, there is a need to be able to reduce any uncertainties about the amount of exposure that they have received. While many devices are available for personnel neutron dosimetry, and enhanced understanding of the energy response of each device is needed. This project explores the relative response of bubble dosimeters to several different types of neutron measurement systems when exposed to three different fast neutron sources. computer simulations when exposed to three different fast neutron sources. Computer simulations of the neutron source and detectors. These data are used to develop comparisons of neutron detector responses for fast neutrons. Correction factors are determined for several of the detectors for 14 MeV neutrons to extend the useful energy range of these devices.
