S>A method of testing fuel elements for surface U contamination below 1 mu g/foot is described. The fuel element is placed in an Al sleeve and surrounded by two semicylindrical ZnS phosphors. The phosphors are optically coupled to a photomultiplier-amplifier-counter arrangement. The fuel element, phosphors, and photomultipliers are placed in a neutron flux of approximately 10/ sup 8/ neutrons/cm/sup 2/sec and the fuel element is lowered past the phosphors at 4 in./min. Contamination is revealed by scintillation detection of fission fragments. (T.R.H.)
