Neutrons from a americium-beryllium source with a source strength of 5 Ci have been examined for shielding using a borated polymer composite formulated of baryte and quartz as strengtheners. It is observed that there is a considerable dose reduction and spectral hardening leading to energy degradations. Various sources of americium have been tried with a target nucleus of beryllium in this experiment for a qualitative estimation of dose reduction. The peaks in the spectra reveal the residual carbon6C12nucleus due to excited neutrons. Use of boron for neutron capture capability and low-Z element polymers for high elastic scattering cross section has contributed to the energy reduction as per the spectrum.
