The annual radiation usage has increased in medical applications and environmental radiation measurements with the consequence that a real-time radiation monitoring system is needed for safe radiation detection. In this study, we developed a new radiation detection system composed of an optical fiber scintillator (OFS) and a photomultiplier tube (PMT). Light of about 400 nm is transferred from the OFS sensor to the detector by using an optical fiber. The results for the sensitivity of the scintillation fiber sensor are reported in this work. We also show -ray detection with 32P. We compared the experimental results with the MCNPX Code simulation results for the same condition. For future applications, the optical fiber scintillator will be studied and compared to a 2D real time radiation imaging system; to other factors such as cost and geometry will be
