Zusammenfassung:	A lightweight, low energy neutron radiography inspection device (20) includes an inspection head (22) with a sealed tube neutron generator (44) using a deuterium target (110) for emitting relatively low energy neutrons. A moderating fluid (140) within the head is used to thermalize the neutrons emitted from the neutron source. A collimator (40) directs the thermalized neutrons to produce a thermal neutron radiograph. The relatively low energy neutrons produced by the neutron generator permit the reduction in volume of moderating fluid required and thus the use of a smaller, more maneuverable, inspection head.
