Nuclear and pressure sensitive line/perimeter detection system

A nuclear radiation and pressure sensitive line/perimeter detection system, comprising:

• a radiation sensitive circuit comprising:
• at least one nuclear-radiation sensitive fiber for producing scintillating photons in the presence of nuclear radiation;
• said fiber comprising an organic scintillator embedded in a polymer forming an elongated cable;
• at least one light-transmitting optical fiber optically connected to said radiation sensitive fiber for propagation of said photons;
• detector means connected to said optical fiber and comprising a photomultiplier means for receiving said photons;
• electronic means operatively associated with said radiation sensitive fiber for receiving signals generated thereby;
• a pressure sensitive circuit comprising:
• a pressure sensitive fiber, in the form of an elongated cable, operatively associated with said radiation sensitive fiber for detecting pressure;
• said electronic means being operatively associated with said pressure sensitive fiber for receiving signals generated thereby;
• a read-out device electrically connected to said electronic means, said electronic means including logic means comprising an AND gate for transmitting a signal from said radiation sensitive circuit to said read-out device only if a signal from said pressure sensitive circuit is present at said AND gate.
