Performance Evaluation of an Imaging Radiation Portal Monitor System

An organic scintillator-based radiation portal monitor (RPM) prototype system with imaging capabilities has been developed based on the neutron–gamma emission tomography technique. The technique enables rapid detection and precise location of small amounts special nuclear materials, such as plutonium, using time energy correlations between fast neutrons gamma rays from spontaneous fission low false-alarm rates. These capabilities, in addition to state-of-the-art various gamma-emitting sources, novel RPM concept efficiently address global security threats terrorism proliferation weapons. detector approach is simple versatile can easily be adapted for different applications security, public safety, emergency response, radiological surveying. In this work, basic performance parameters at KTH have evaluated.
