The aim of this study was to develop and evaluate fiber-optic sensors for the remote detection of gamma rays in areas that are difficult to access, such as a spent fuel pool. The fiber-optic sensor consists of a light-generating probe, such as scintillators for radiation detection, plastic optical fibers, and light-measuring devices, such as PMT. The (Lu,Y)2SiO5:Ce(LYSO:Ce) scintillator was chosen as the light-generating probe. The (Lu,Y)2SiO5:Ce(LYSO:Ce) scintillator has higher scintillation efficiency than the others and transmits light well through an optical fiber because its refraction index is similar to the refractive index of the optical fiber. The fiber-optic radiation sensor using the (Lu,Y)2SiO5:Ce(LYSO:Ce) scintillator was evaluated in terms of the detection efficiency and reproducibility for examining its applicability as a radiation sensor.

Tumor therapy using the high-energy radiation has evolved over the decades as typical non-invasive treatment method due to its advantage compared with surgery. But, the radiotherapy can damage or destroy normal cells as well as destroying tumor cells and cause side effects of treatment. Even though most side effects are temporary, these effects can be extremely fatal for patient. Therefore, the exact measurement of the exposure dose of patient during radiation therapy is very important for patient safety. In the case of the conventional fiber-optic radiation sensor that consists of a scintillator for high-energy radiation dosimetry, additional correction is necessary due to the quenching effects of the scintillator. In this study, we measured the exposure dose of the high-energy proton beam without the scintillator by using the Cerenkov radiation that generated inside the plastic optical fiber. As a result of this study, we confirmed a Bragg peak of the proton beam without a scintillator. Also it was in good agreement with the result of the ionization chamber.
