Abstract

The feasibility of using a combined sample of borated polyethylene and normal polyethylene to estimate neutron ambient do equivalent from measured prompt gamma emission sisi investigated theoretically to demonstrate improvements in low energy neutron do se response compared to only polyethylene. Monte Carlo simulations have been carried out using the FLUKA code to calculate the response of boron, hydrogen and carbon prompt gamma emissions to mono energetic neutrons. The weighted least square method is employed to arrive at the best linear combination of the responses that approximates the ICRP fluence to do se conversion coefficients wellintheenergyrangeof10_8 MeV to14MeV.The configuration of the combined system is optimized through FLUKA simulations. The proposed method is validated theoretically with five different work place neutron spectra it satisfactory outcome
