X or Gamma radiation is used for troubleshooting, checking the homogeneity welds, corroded areas of research etc ...
The materialization of the images or sound material defect is obtained on a photographic type film.
It is possible to determine the residual thickness of materials or search inhomogeneities in structure density (lead, concrete ...) by the implementation of the method gammamétrique using radionuclides such as 192 and Ir Co 60 associated receptor type counter or ionization chambers.
We use this technique:
