Abstract
A method for detecting ionizing radiation, a detector ( ) for detection of ionizing radiation, and an apparatus for use in planar beam radiography, including the detector. The detector includes: a chamber filled with an ionizable gas; first and second electrode arrangements ( ) provided in the chamber with a space between them, the space including a conversion volume ( ); an electron avalanche amplification unit ( ) arranged in the chamber; and, at least one arrangement of read-out elements ( ) for detection of electron avalanches. Radiation enters the conversion volume between the first and second electrode arrangements via a radiation entrance. The distance between the first and second electrode arrangements is selected to achieve discrimination of fluorescent photons and/or long-range electrons, in order to achieve improved position resolution.
