Abstract : Neutron radiography was studied as a method for the nondestructive examination of loaded Army munitions items. A ten-milligram Californium-252 source was acquired and facilities for its use as a primary neutron source were developed. A versatile source-handling mechanism which accommodates a number of different experiments was devised by modifying a standard cobalt-60 source system, and was incorporated as an integral part of the storage/shipping container. Two moderator designs have been used thus far. Applications of neutron radiography using the californium source have included 100 percent examination of a pilot production run of 1,300 explosive boosters, as well as a variety of other small munitions items.
