Abstract Objective To study the relationship of different enamel sample mass and their enamel ESR signal intensities in order to find out a suitable mass range used in dose reconstruction.Methods The enamel samples are prepared from non-irradiated adult teeth by mechanical crash.The samples with different mass are scanned by an ESR spectrometer after their irradiation by 60Co γ rays.Results The linearity between ESR signal response and mass is not good in the range of 10~200 mg.But the linearity between ESR signal response and mass is good in the range of 40~120 mg.Conclusion It is better to choose enamel samples with the mass in the range of 40~120 mg in dose reconstruction.
