    Abstract

    The Los Alamos Scientific Laboratory has investigated and used radiography, ultrasonics, sonics, eddy current, radiation gaging, and beta-backscatter gaging for the inspection of graphite and its protective coatings. Some applications and limitations of these techniques are reviewed. The use of ultrasonics, sonics, eddy current, and radiation gaging to determine physical characteristics, aside from the normal flaw detection, shows promise in the inspection of graphite. Electron microscopy has proved to be a valuable tool for the evaluation of the findings of nondestructive testing.
