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