Abstract
A primary radiation diaphragm for a radiation apparatus has at least one diaphragm plate which is adjusted in a plane extending perpendicular relative to the central ray of radiation. Each plate is provided with a single mount which engages a guideway disposed on the wall of the housing. Preferably, four plates are arranged in two pairs, with the first pair lying in a first plane and the second pair lying in a second plane extending parallel to the first pair, each of the plates of the pair has a single mount and the pair of plates of the first pair engage the same guideway, while the pair of the second plate engage a second guideway disposed on a wall of the housing extending at right angles to the first-mentioned wall.
