A neutron irradiation experiment was performed to determine the neutron absorbed dose rate response of a criticality accident alarm system detector. For this purpose, the authors tailored a neutron field by the use of a 252 Cf neutron source and 50-mm-thick lead blocks, which removed unwanted gamma rays emitted from the source itself while allowing the neutrons to pass through. The evaluated neutron response of the detector was confirmed to be in reasonably good agreement with the prior computer-predicted response.
