Composite gamma-neutron detection system

A system for detection of neutrons and gamma rays, comprising:

• a plurality of scintillator screens comprising thermal neutron absorber materials, said materials interacting with neutrons to emit heavy particles, and said heavy particles interacting with scintillator screens to produce light,
• a plurality of light guides into which said scintillator screens are embedded, said light guides serving as a neutron moderating medium,
• a first photodetector which receives the produced light through said light guides, and converts the light to a measurable signal,
• a plastic scintillator for producing light on interaction with gamma-rays,
• a reflector placed between said plastic scintillator and said scintillator screens to prevent cross-contamination between optical signals from the neutron and gamma detection materials, wherein the reflector is positioned in parallel to said plastic scintillator and said scintillator screens,
• a second photodetector which collects the produced light from said plastic scintillator, and converts the light to a measurable signal, and
• a first counter and a second counter for counting pulses generated by the first photodetector and the second photodetector, respectively.
