Abstract (en)
[origin: ES8106210A1] The invention relates to a converter for converting non-luminous, so-called input photons such as X or gamma photons, into luminous photons, and to an installation for the non-destructive inspection of a material, employing this converter. The converter comprises a layer of luminophore disposed on the path of said non-luminous photons and, upstream of said layer of luminophore, with respect to the direction of displacement of the non-luminous photons, a metal foil in which said non-luminous photons are converted into non-luminous photons of lower energy, by collision (Compton effect) of said input photons on electrons of said metal foil. The invention is more particularly applicable to the non-destructive inspection of concrete structures.
