In this paper, we report investigations of the detector characteristics for boron-loaded plastic scintillators for neutron measurements. The detectors were tested with fast neutrons emitted from fission decays of a 5-μCi 252Cf source and with slow neutrons provided by the MC50 cyclotron at the Korea Institute of Radiological and Medical Science. The energy spectrum of the fast neutrons was obtained by applying a time-of-flight method to the coincident measurement of neutrons and gamma rays emitted from fission decays. The detectors were also tested to perform a pulse-timing analysis for fast neutrons, slow neutrons, and gammas to understand the scope of the discrimination for gamma rays when the detector is applied to practical measurements.
