Regulations on nuclear power state requirements for measurements of personal dose equivalent at the depth of 70 micrometers for exposures, where the maximum dose can be appeared at body parts except the torso. The hands doses have been measured with Thermal Luminescence Dosemeters in the Nuclear Science Research Institute (NSRI) in the Japan Atomic Energy Agency. In this study, we developed a new ring type dosemeter using the optically stimulated luminescence elements. We have inspected the characteristic by irradiation examinations and a Monte Carlo simulation and established dose evaluation method.
