Incipient Leak Detection Using Radioactive Krypton 85.
Abstract
In this study, a method for detecting incipient leakage in stored munitions was investigated using an inert radioactive gas, krypton 85, as the inspecting medium. Krypton 85, a beta particle and gamma radiation emitter, pervaded small fissures and corrosion pits which progressed with time. When these defects came sufficiently close to the containers' outer surfaces, the relative attenuation of beta particles provided the mechanism for defect detection. Both simulated and natural corrosion were detected and measured in test standards. In a surveillance program, closed end-items were monitored from the time of fabrication, and natural corrosion pits were located and measured when pitting had penetrated less than 20% of the items' thickness in areas of interest. This process is considered to have significant potential for detecting incipient leakage. (Author)
