Abstract

The article describes the testing of radiographic technical films according to the regulations of GOST R ISO 11699-1–2023 and according to the method developed at NRC «Kurchatov Institute» – VIAM. The obtained informative characteristics of radiographic films are compared. The article shows that obtaining a characteristic curve according to the requirements of GOST R ISO 11699-1–2023 does not take into account the influence of X-ray radiation energy. The properties of the analog of the characteristic curve according to the developed method take into account its dependence on the radiation energy, i.e. it determines not only its sensitometric properties, but also its flaw detection properties.
