Neutron energy response of a modified Andersson-Braun rem counter

The fluence response of three models of Andersson-Braun (A-B) rem counters in neutron radiation fields with different neutron energies has been investigated. In three monoenergetic neutron fields of higher energy and two high energy stray radiation fields the response of the modified A-B rem counters is better than that of conventional A-B counters. In the field of high energy neutron radiation, underestimations of the neutron dose equivalent will be unavoidable with the conventional A-B rem counter.
