The fluence rate distribution of neutrons in the reactions of 50 MeV/u 18 O ion on thick Be, Cu and Au targets have been measured with an activation method of threshold detectors and the neutron dose equivalent rate distributions at 1 m from the targets in intermediate energy heavy ion target area are obtained by using the conversion factors from neutron fluence rate to neutron dose equivalent rate.
