Comparison of light transport-incorporated MCNPX and FLUKA codes in generating organic scintillators responses to neutrons and gamma rays

The NE102 plastic scintillator response to 137Cs gamma rays and NE213 liquid scintillator response to both mono-energetic and 241Am-Be neutrons have been modeled using FLUKA׳s EVENTBIN and MCNPX׳s PTRAC cards. The comparison made in different energy regions confirms that the overall difference is less than 6%.
