Abstract
The invention relates to an x-ray dosimeter comprising a first capacitor plate (1) and a second capacitor plate (2) which are arranged in a chamber or form parts of a chamber (4), said chamber (4) being filled with a gaseous medium. The first capacitor plate (1) comprises an active measuring field (5) on the side thereof facing the second capacitor plate (2), and the second capacitor plate (2) comprises an electron-emitting x-ray absorption layer (6) on the side thereof facing the first capacitor plate (1).
