A novel real-time optical fibered dosimetry system based on optically stimulated luminescence (OSL) of SrS:Ce,Sm phosphor was developed and is presented. The advantages of this system are the combination of OSL and optical fibers, immediate readout, simplicity of use, low cost, reliability, flexibility, and robustness. Experimental results show an excellent linearity with the dose (0.01 to 6 Gy), repeatability better than 2%, radiation sensitivity up to 80 mV cGy 1 and accuracy since error on dose is less than 5%. The applications targeted are the measurement of the dose delivered during a treatment in radiation therapy and the monitoring of the dose or dose-rate around or in nuclear reactor and accelerator facilities in high energy physics. Further experiments are still to be conducted in order to fully characterize the system and evaluate the feasibility of each application mentioned.
