Abstract :
A scintillator-based gamma-ray detection system that uses a radiation-resistant optical fiber was developed. The system consisted of two radiation-resistant optical fibers—one, a fiber with a scintillator, and the other, a fiber without a scintillator—which were used to obtain the gamma-ray dose rate at the measurement point. This system demonstrated a linear response with respect to the gamma-ray dose rate from 0.005 to 1.5 Gy/h and a good radiation resistance over an absorbed dose of more than 300 kGy.
