Experimental optimization of a landmine detection facility using PGNAA method

Hakimabad Hamed

Abstract

The optimum moderator geometry increases the performance of prompt gamma neutron activation analysis (PGNAA) method considerably.In this work an ~(241)Am-Be source was used in the moderator geometry for detecting buried landmines by PGNAA method.Experiments were done to find the best moderator geometry for the moderated ~(241)Am-Be source,by replacing the mine with a neutron detector and counting the thermal neutron flux.The flux of thermal neutrons at the place of mine was used as a determining factor to introduce the best moderator geometry.
