Abstract: This paper reports on the study of thermostability of radiated trapped electrons in tooth fossil. The samples of tooth fossil were collected from the Peking-Man site at zhoukoudian. We made a comparison of thermostability between enamel and dentin and got that the mean-live of the ESR signal (g=2.0016) is 7.1×106 years (20℃). The result shows that it is reliable to date by this signal (g=2.0016). Choosing enamel sample for dating is more appropriate.
Key words: Mean-life, Enamel, dentin
