Neutron energy spectrum measurement of four different shielding materials namely water, baryte colemanite, lead and paraffin were done using Radial Piercing Beamport at reactor TRIGA PUSPATI (RTP) in Malaysian Nuclear Agency. This beamport is installed with highly oriented pyrolytic graphite (HOPG) mosaic crystals as monocromator. The neutron energy of thermal neutron, fast neutron and gamma of these materials were measured using two types of neutron detectors. The first detector is a liquid scintillator of type NE213 for detecting neutrons with energies from 800 keV to 20 MeV. The second detector is the 3He gas that is suitable to detect spectrum of thermal neutrons up to 1.5 MeV neutrons. The effect of different type of materials and their arrangement/combination to the neutron energy spectrum will be studied to provide suitable arrangement for effective shielding for use in neutron beam installation at RTP .
