We have developed realtime in vivo dosimetry system based on a micro plastic scintillator with an optical fiber for Ir¹⁹² brachytherapy for uterine cervix cancer. The purpose of this study was to investigate the physical property of this dosimeter including the linearity, temperature, angular and energy dependences using our original phantom.
