Abstract:

The fast neutron radiography system described is in an early state of development, but the results obtained to date suggest that it could become a truly useful nondestructive testing technique. It has the potential for competing with thermal neutron radiography in its ability to image hydrogen-containing materials such as phenolics and plastics, and appears to be of general radiographic use in the same manner as x-radiography while retaining good penetrating ability. The use of californium-252 as a source of neutrons provides radiation emitted in all directions allowing simultaneous exposures to be made over the full surface of a sphere surrounding the source, thereby increasing its efficiency many-fold.
