Is an abnormal radioactive target on target? (Section One) which will appear on the advertisement page: 1. The judgment method determines the presence or absence of abnormal radioactive material in the target in the area of detection. The methodology includes (i) obtaining the target gamma spectrum from the target, (ii) the provision of a target dataset consisting of multiple intensities from the target gamma spectrum, where each intensity value is Relative to the energy input unit representing the gamma radiation energy or the energy range:
