Abstract:
1. A radiation detecting system comprising: an optical fiber cable adapted to emit light at a region where radiation is applied and transmitting the emitted light, photoelectric conversion means connected to at least one end of said optical fiber cable, and processing means detecting when radiation is applied in accordance with an output signal of said photoelectric conversion means, wherein said optical fiber cable further includes at least one detect portion, wherein the light emitted at said detect portion when radiation is applied to said detect portion is transmitted within said optical fiber cable, and wherein said optical fiber cable further includes: an optical fiber having an optical transmission core extending along one direction to transmit light emitted at said detect portion; a clad layer covering over a peripheral surface of said core; and a scintillator material dispersed in said clad layer and emitting light when radiation is applied, a radiation-shielding layer covering substantially over a periphery of said optical fiber, wherein a gap is provided with locating in at least one part of said radiation-shielding layer as said detect portion, and wherein said gap is formed over the entire length in the circumferential direction of said optical fiber.
