Title: Study on electron spin resonance dosimetry of dog tooth enamel
Abstract:Four groups dog tooth enamel samples were irradiated with different dose by 137Cs γ-rays.Their electron spin resonance(ESR) spectra pre-and post-irradiated were measured and the changes of ESR signal ...Four groups dog tooth enamel samples were irradiated with different dose by 137Cs γ-rays.Their electron spin resonance(ESR) spectra pre-and post-irradiated were measured and the changes of ESR signal intensi-ties were analyzed.The results showed that the average intensity of native signals of dog tooth samples was 20.8±2.9,much weaker than that of human 39.5;the dosimetric signal intensities of dog tooth enamel increased with the ab-sorbed doses;the mass of each sample is 100 mg.The average irradiation response of dog tooth enamel samples was(37.1±2.1) Gy-1,very close to that of human tooth samples(36.3 Gy-1).The dog tooth can be used for retrospective dosimetry when human tooth are difficult to collect.Read More
