Development of a Tissue Equivalent Proportional Counter System for the Measurement of Neutron Dose.
Abstract
This paper describes a neutron-gamma dose measurement system utilizing a Tissue Equivalent Proportional Counter (TEPC). A multi-channel analyzer acquires the data and sends it to a personal computer for analysis on a spreadsheet. The system yields information on lineal energy, absorbed dose, quality factor and dose equivalent for different neutron-gamma sources. Results are presented which compare the response of the TEPC system to a thermoluminescent detector (TLD), neutron remmeter (AN/PDR-70), and a liquid scintillator (NE-213) with exposure to Californium, Plutonium-Beryllium and 14 MeV neutron sources. Quality factor comparisons are shown between the TEPC system, which measures lineal energy, to presently accepted quality factors, which are based on linear energy. The results of the project indicate that the TEPC should be given serious consideration for use as a shipboard area dosimeter. Keywords: Dosimeters; Radiation dosimetry; Radiation; Safety measures.
