Abstract：
This paper describes the principle and construction of a modified Andersson-Braun(A-B) neutron rem counter which is used for the stray radiation field of high energy accelerator. The energy responses from thermal neutron to 45.4MeV semi-monoenergetic neutron experiments with four kinds of A-B rem counter were carried out using a few of neutron generating facilitiest The response investigation of A-B rem counters for the stray radiation field outside shielding of 12 GeV proton accelerator was completed. The results show that in the high energy neutron radiation field, the response of modified A-B rem counters is better than that of conventional A-B rem counters.
