Simulation of a Compact Multi Element Tissue Equivalent Proportional Counter Response in Low Energy Monoenergetic Neutron Fields

Abstract

A Tissue Equivalent Proportional Counter (TEPC) directly measures dose equivalent delivered by a radiation field to human tissue. TEPC technology has great potential for use in low energy neutron fields, such as those in nuclear power plants, however, what hinders its use as a portable or personal dosimeter in such fields is its large physical size. To address this technology gap, a Compact Multi Element Tissue Equivalent Proportional Counter (CMETEPC) has been developed. This paper describes the process of designing the CMETEPC and discusses how this counter performs in low energy monoenergetic neutron fields relative to established TEPC designs.
