This paper described a measurement of accelerator neutron radiation field at transport beam line Beijing-TBF. The experiment place was be selected around Faraday Cup with graphite target impacted by electron 2.5GeV. First all, we simulated the FLUKA. Secondly, chose six appropriate ERNMS according to their fluence response function measure count rate. Then U_M_G package program utilized unfolding data. Finally, drew comparison between simulation spectrum and made an analysis about result.
