Integrated X-ray detection system for determination of nuclear material concentration
An integrated system of X-ray Absorption Spectrometry (XAS), also called L-edge densitometry for uranium (LED) and X-ray Fluorescence spectrometry (XRF) is designed using Monte Carlo simulation for determining concentration of uranium and minor actinides for safeguard. The system can be useful to determination uranium and minor actinide, such as plutonium, neptunium, and etc., concurrently. The equipment is compact compared to the K-edge densitometer with high purity germanium detector which needs liquid nitrogen cooling since a low energy X-ray source is used. The system has been validated from simulation and analysis of the transmitted and reflected spectrum. The concentrations of nuclear material samples are obtained from this study. (authors)
