Abstract: A detector (10) for high-energy radiography includes, in the following order: a metal screen (12) arranged to receive incident radiation, at least part of the incident radiation being transmitted through the metal screen and forming a transmitted radiation, a scintillator component (14) arranged to convert the radiation transmitted by the metal screen into light, and a detection layer (16) arranged to detect the intensity of the light emitted by the scintillator component. The screen (12) is made of a metal having an atomic number that is strictly greater than 70 or is made of an alloy comprising at least 50% mass content of one or more metals having an atomic number that is strictly greater than 70 and in that the thickness of the screen is between 20 ?m and 900 ?m.
