本研究的目的是直接测量在灾难发生时居住在距离福岛核电站80 km范围内的福岛居民，并在灾难发生后继续居住至少3个月的志愿者牙齿中可能的辐射诱导EPR信号。本研究招募了34名志愿者。这些测量是使用便携式L波段EPR光谱仪进行的，该光谱仪最初是在达特茅斯的EPR中心开发的。所有测量均使用专门为上门牙设计的表面环路谐振器进行。潜在地，这些信号不仅包括由事件引起的辐射引起的信号，而且还包括背景信号，包括来自环境和医疗暴露的先前辐射暴露的那些信号。我们证明了将剂量计运送到测量地点并进行有效测量是可行的。所获得的信号强度并没有明显高于在福岛没有潜在辐射暴露的志愿者所看到的信号。
The aim of this study was to make direct measurements of the possible radiation-induced EPR signals in the teeth of volunteers who were residents in Fukushima within 80 km distance from the Fukushima Nuclear Power plant at the time of the disaster, and continued to live there for at least 3 month after the disaster. Thirty four volunteers were enrolled in this study. These measurements were made using a portable L-band EPR spectrometer, which was originally developed in the EPR Center at Dartmouth. All measurements were performed using surface loop resonators that have been specifically designed for the upper incisor teeth. Potentially these signals include not only radiation-induced signals induced by the incident but also background signals including those from prior radiation exposure from the environment and medical exposure. We demonstrated that it is feasible to transport the dosimeter to the measurement site and make valid measurements. The intensity of the signals that were obtained was not significantly above those seen in volunteers who had not had potential radiation exposures at Fukushima.
