Neutron radiography in field use
Some of the basic aspects of neutron radiography are reviewed with particular emphasis on the physics of this nondestructive testing method. The results of an experimental evaluation program are presented which show conclusively that isotopic antimony-beryllium photoneutron sources can be used for neutron radiographic applications. This program provided valuable new information regarding neution moderation and beam collimation requirements. Based on this experimental evidence, a portable device was designed and is described. The device employs a portable radiographic camera, with im antimony- beryllium photoneutron source, in conjunction with a neutron moderator and beam collimator configuration. This development makes available, for the first time, a means of obtaining economical inspection neutron radiographs in field application usage. (auth)
