英文摘要
The measurement of ESR background signals from human isolated teeth using L-band ESR spectrometer was carried out. The average of the ESR signal intensity was 0.017014±0.011049 a.u. (arbitrary units). The histogram analysis revealed that the distribution of the background signals obeyed a log-normal distribution. We confirmed that the serial irradiation by a diagnostic dental X-ray imager generates detectable ESR signals by L-band ESR spectrometer. It is suggested that medical exposures e.g. diagnostic dental X-ray imager mainly generate ESR background signal in human teeth. The addition of certain signal intensity seems to be acceptable procedure as a correction method.
