Development of a technique using MCNPX code for determination of nitrogen content of explosive materials using prompt gamma neutron activation analysis method

► In this study we used melamine (99.8% purity) which has a similar composition to the explosive compounds. ► In the present study, tiny amounts of samples were detected using the peak areas of hydrogen and nitrogen. ► In this study a point neutron source 252Cf was used for neutron irradiation of samples. ► In this work the mH/mN ratio was calculated using three techniques. ► This study showed that MCNP4c results and measurements were in good agreement.
