Description

The enamel samples from cow teeth and human teeth were irradiated with 137Cs γ ray. Their electron spin resonance (ESR) spectra pre and post-irradiation were weaker than those of human. Mass of each sample is 100 mg, the dosimetric signal intensity of cow enamel increased with the radiation dose; the averaged radiation response of cow samples was (34.4±2.0) Gy-1, very close to the average response of human tooth samples (36.3±2.9) Gy-1. Therefore cow teeth can be used for retrospective radiation dosimetry when human teeth are unavailable. (authors)
