In 1960 at the McGuire Air Force Base, New Egypt, New Jersey a helium tank ruptured causing a fire to ignite a nearby nuclear tipped Boeing Michigan Aeronautical Research Center BOMARC missile. During the fire the weapons grade plutonium Pu-239, Pu-240, and Pu-241 ignited and was released into the surrounding area, due to both fire-fighting efforts, where high pressure water was used to put out the fire, as well as smoke that deposited plutonium as oxidized particles in the surrounding area Cicotte, 2007. This study investigates the heterogeneity of the distributed plutonium contamination in the McGuire Air Force Base BOMARC missile site soil based upon direct measurements of Am-241, a decay product of Pu-241. The heterogeneity of soil samples taken from the BOMARC missile site was quantified using a conjugate counting method with gamma spectroscopy analysis. Plutonium was shown to be heterogeneously distributed in the BOMARC missile site soil. The physical properties of the heterogeneously distributed plutonium contamination evaluated in this research likely consist of individual particles of plutonium metal alloys. The fate of these particles in the environment as they continuously are exposed to weathering and other physical factors is unknown.
