| Outline of Final Research Achievements |
We conducted experiments regarding to the equipment for practical usage of EPR portable spectrometer, and also evaluated measurements with volunteers, and analyzed the detection limit of this device. 34 volunteers in Fukushima prefecture participated the practical measurements. As the results, ratio of EPR signal intensity versus standard signal intensity with PDT was 0.087±0.051. The intensity of the signals that were obtained were not significantly above those seen in volunteers. The detection limits for radiation exposures are calculated. The sensitivities are 77.0%, 99.9% and specificities are 78.0%, 99.8% with 1Gy, 2Gy exposures respectively under ex-vivo condition. We demonstrated that it is feasible to transport the dosimeter to the site and make valid measurements as a triage purposes with high dose (>2-4Gy).
