Abstract. Though fast neutron contribution in a thermal imaging beam line is typically considered as a burden, we have investigated its application for imaging using the high energy tail of the fission spectrum at a reactor beam line. Fast neutron imaging is a promising non-destructive technique for testing dense and voluminous objects of practically any material composition. Fast neutron radiography and tomography have been performed using the RAD beam line of the 10 MW research reactor of the Budapest Neutron Centre (BNC), Hungary, using a camera-based imaging detector system on different bulky objects (up to 150 mm in diameter) and the results are presented here.
