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 movement algorithm was optimized by decision trees analysis. According to the proposed algorithm, a 137 Cs point source was identified using a multi-pixel CdTe detector mounted on an unmanned vehicle as a prototype 4π gamma imager.
