Gamma-ray sensing probes operating under the Cerenkov effect measure the burnup of spent nuclear fuel assemblies. The probes include an optical fiber that reacts to gamma rays coming from the spent nuclear fuel assembly and emit light via the Cerenkov effect. A scatterer surrounds the optical fiber to increase the light emitting efficiency of the optical fiber by the Compton electron scattering. A collimator composed of shielding material surrounds the scatterer. The collimator has a slit groove which is open in one direction for directing the gamma rays from the spent fuel assembly to the scatterer.

The present invention relates to a fiber-optic sensor system for measuring the relative dose of a therapeutic proton beam by measuring Cerenkov radiation and a method of measuring using the same, and more particularly to a fiber-optic sensor system for precisely and economically measuring a proton beam by measuring the Cerenkov radiation generated from a fiber-optic sensor and a method of measuring using the same. The present invention comprises a proton beam source, a fiber-optic sensor for measuring the Bragg peak of the proton beam and SOBP, an optical detector for measuring the Cerenkov radiation, and a pair of optical fibers connecting the fiber-optic sensor and the optical detector, wherein the fiber-optic sensor being irradiated with a proton beam, the Cerenkov radiation generated in the optical fibers themselves is delivered through the optical detector to an amplifier system, and the resulting signal is transferred to a computer.
