- Abstract
- In this study, we developed a remote gamma spectroscopy system based on fiber-optic radiation sensor (FORS) to detect species of gamma-emitting sources at large distances. In order to evaluate the performance of the gamma spectroscopy system, we measured the scintillating light intensity and gamma energy spectra as a function of the length of the plastic optical fiber (POF) and radioactivity of the gamma-ray source. Using the obtained experimental results, we selected the optimal inorganic scintillator as the FORS sensing material and measured the energy spectra. In addition, the photopeaks of the gamma-emitting sources were detected for different lengths of the POF and radioactivity of the Cs-137 gamma-ray source. It is expected that the remote gamma spectroscopy system based on FORS can be an effective and convenient tool that can detect gamma-emitting sources at large distances, and can identify species of radioactive sources by measuring gamma energy spectra in nuclear facilities.
