Material inspections by different methods of neutron radiography-specific problem solutions

摘要

This paper gives an overview about the investigation of technical objects and processes by different neutron radiography methods in order to solve several tasks and problems nondestructively. It is important to mention that for each problem, the approach was tried which seemed to be best suited. This was possible due to the high flexibility in respect to variable beam conditions at the NEUTRA and the NCR stations at SINQ and the different detection methods available. In some cases, the limitations of neutron imaging were reached, caused by too low transmission through the objects or missing sensitivity to certain materials. The comparison and the complementaries to conventional X-ray techniques can complete the inspection of objects in some special cases by parallel application.
