In the Japan Atomic Energy Agency (JAEA), exposures to fingertips can be significant in radiological decontamination at the facilities with mixture fields of beta and 
(X) rays. The radiation doses to fingertips have been measured by ring type dosemeters equipped with thermoluminescence dosemeters (TLD) in JAEA. We applied small Optically Stimulated Luminescence (OSL) elements to the ring type dosemeter, which has the advantages in the use for long term and repeating in dose measurements comparing to the TLDs. In this report, we introduce the outline and the dose evaluation method of the new ring type dosimeter which we applied.

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.

Nuclear Science Research Institute is assisting activities concerning the accident of the Fukushima No.1 Nuclear Power Station including the environmental monitoring and the resident's house decontamination, etc. In these assistance, we executing the personal monitoring to assistance staff, because there was fear of the external exposure and the internal exposure. We did by the measurement and the evaluation method of the personal monitoring in consideration of the rise of the environmental background level. We introduce the method of use to evaluate the exposed dose etc.
