Most methods of hydrogen isotopes analysis in construction and functional materials only enable to form an opinion about integral quantities of their concentrations failing to provide information about hydrogen distribution in the sample. A new highly-informative analysis technique such as radioluminography allows estimating, to a high precision, the content and distribution of tritium in different materials. It’s a new possibility for investigations of hydrogen interaction with the construction and functional materials. Radioluminography technique enables to deteсt tritium diffusion coefficient over a wide temperature range, even where the application of membrane methods is difficult. The use of various types of IP plates allows detecting tritium as to beta-radiation and X-ray bremsstrahlung. The paper provides examples of the application of the radioluminography method for the qualitative and quantitative determination of tritium on the surface and in the near-surface region of the sample.
