An Experimental Neutron Radiography System Using Californium-252.
PICATINNY ARSENAL DOVER N J
Pagination or Media Count:
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 storageshipping 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.
