摘　　要：To monitor the integral dose deposited in the BESⅢ electromagnetic calorimeter whose performance degrades due to exposure to the BEPC Ⅱ background, a 400 nm IMPL RadFET dosimeter-based integral dose online monitor system is built, After calibration with the ^60Co source and verification with TLD in the pulse radiation fields, an experiment was arranged to measure the BEPC Ⅱ background online. The results are presented.To monitor the integral dose deposited in the BESⅢ electromagnetic calorimeter whose performance degrades due to exposure to the BEPC Ⅱ background, a 400 nm IMPL RadFET dosimeter-based integral dose online monitor system is built, After calibration with the ^60Co source and verification with TLD in the pulse radiation fields, an experiment was arranged to measure the BEPC Ⅱ background online.
