The rapidly increasing peacetime application of nuclear energy will entail a corresponding increase in the use of uranium. The high physical density, nuclear characteristics, slightly different manufacturing methods, and greatly unorthodox specifications for uranium require special techniques of nondestructive testing. Uranium ranging in thickness from a few mils up to about 2 1/2 in. has been radiographed successfully, using sources of different energies. Typical exposure charts, respective film-screen combinations, the use of vacuum cassettes, and the problem of shielding against object and room scatter are also included in this discussion. Furthermore, the use of radiation gages to measure the uniformity of mass per unit area and the application of ultrasonics are taken under consideration. The sensitivities of these various methods, which determine their use within a particular thickness range, are also mentioned.
