Description
During neutron irradiation in Prompt Gamma Neutron Activation Analysis (PGNAA), absorption of thermal neutrons by the detector is inevitable. Therefore, the final gamma spectrum will be a mixture of natural background, delayed and prompt gamma-rays originated from different setup parts including moderator, sample and detector itself. A Delayed-Gamma-Monte-Carlo Code (DGMC) was written to determine delayed gamma neutron activation spectrum arising from an active detector. Spectral response of 3"×3" Na(Tl) crystal to thermal neutron beam was also simulated while the neutron beam was ''on".
