During study period, we developed the monitoring sensor for individuals equipped with radioactivity monitoring, acceleration, temperature and electrocardiogram perceptional function. Using this monitoring sensor, we evaluated the biological information of dispatched medical stuff from Nagasaki University Hospital after the accident at Fukushima Daiichi nuclear power plant accident following Tohoku Region Pacific Coast Earthquake on March 11, 2011. In addition, we evaluated the internal radiation exposure doses of dispatched persons from Nagasaki to Fukushima by the precision model of whole body counter which were setting in Nagasaki University. Particularly, from the subject who measured after an accident at initial phase, short half-life radionuclides such as I-132 and Te-132 I-131 were detected, which gives to the important information on the situation of accident.
