NEUTRON RADIOGRAPHY--A NEW DIMENSION IN RADIOGRAPHY
The potential advantages of neutron radiographic inspection methods for metals are discussed. Primarily these advantages are associated with the relative differences in the absorptive properties of materials for neutrons as compared with gamma or x rays. These absorption differences can be used in many cases to obtain improved discrimination between several materials which may be present in an object under inspection. In addition, because of the higher transmission of thermal neutrons through most heavy metals, there are advantages to be gained in employing neutron techniques for the inspection of such materials. A comparison of neutron and other radiographic inspection methods for the inspection of U, in particular, is given. It is shown, using available neutron sources, both radioactive and accelerator, that significant gnins in exposure time can be achieved over most other radiographic equipment. Using a reactor neutron source, the speed of the neutron inspection method would surpass that of a 22 Mev betatron for U radiography. It is also shown that thes gains can be achieved while maintaining high image quality since contrast sensitivities in the order of 1 to 2% were obtained. (auth)
