Electron spin resonance (ESR) measurement was conducted for 11 teeth donated by 10 atomic-bomb survivors in Hiroshima. The ESR signal intensity and chromosome aberration frequency in lymphocytes of the tooth donors showed a good correlation. In one exceptional case, however, high chromosome aberration frequency failed to accompany any sign of radiation exposure in tooth enamel. The sample was found to be a wisdom tooth and the donor was 15 years of age at the time of bombing, raising a possibility that the enamel of the tooth was not completely developed at the time of radiation exposure. Our experience shows importance to collect detailed information on the donors whose biological materials were used for radiation dose reconstruction.
