Optimization of Detector Movement Algorithm Using Decision Tree Analysis for Radiation Source Identification Based on 4π Gamma Imaging

Abstract

For accurate identification of radiation sources using 4π gamma imaging, the selection rule of measurement points around target sources was investigated. In a simple computational model of the 4π gamma imaging, the detector transfer algorithm was optimized by decision tree analysis. According to the proposed algorithm, a 137Cs point source was identified using a multi-pixel CdTe detector mounted on an unmanned vehicle as a prototype 4π gamma imager.
