ESR dating method and the age determination of the first skull of Zhoukoudian Pe king-Man have been introduced in this paper. Some animal fossil teeth

which are contemporaneous with the Peking-Man

were used for determination of accumulative dose. The in-ternal and environmental doses of the tooth samples were determined by neutron activation analysis and embeded thermoluminescence dosimeter at the site

respectively. The age of 578 ka of the first skull of Peking-Man is calculated by the linear uranium accumulation model. According to the ESR dating results

we have given a chronological scale of the cave deposits Loc. 1

Peking-Man site and discussed the mean-life of trapped electron for dating.
