Abstract：
To monitor the integral dose deposited in the BESⅢ electromagnetic calorimeter whose performance degrades due to exposure to the BEPCⅡ 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 BEPCⅡ background online. The results are presented.
