There is currently a nuclear facility’s demand for optical methods to measure gamma radiation. For such measurements, we need very robust measurement methods and sophisticated equipment. Silica optical fibers connected with crystal scintillators are well appropriate, and we present our results from their implementation. The scintillators detect gamma radiation and the silica optical fibers transmit the scintillation light from the scintillator to the detector. We used commercially available silicon optical fibers up to 1.5 mm in diameters with different
numerical apertures to transmit visible light from the scintillators to the detector. This paper presents a properties comparison of various optical fibers suitable for gamma-ray measurements.
