Paper Abstract

In this study, we fabricated an organic scintillator array sensor (OSAS) based the array of organic scintillators. The scintillator array of OSAS for detecting positions of 192Ir gamma-ray source was fabricated using four types of organic scintillators, which emit the scintillating lights of different wavelength, respectively. To evaluate the performance of the OSAS, 192Ir gamma-ray source employed in a HDR brachytherapy was used. In this research, the spectra were measured with positions of 192Ir gamma-ray source which was moved at intervals of 5 mm and 10 mm using the OSAS. The experimental results show that the proposed OSAS can measure and discriminate the wavelength of scintillating lights generated in the OSAS according to the positions of 192Ir gamma-ray source. It is expected that the OSAS can used to detect positions of 192Ir gamma-ray source during a HDR brachytherapy. Further studies are planned to fabricate the OSAS with the different intervals of movements and the small size of organic scintillators.
