An apparatus to handle at least one image recording medium having an essentially flat surface, comprising: a substantially flat housing including two essentially parallel sides having similar dimensions, the housing further including a plurality of relatively smaller-dimensioned edges, at least one edge of the housing including an opening configured to allow passage of the at least one image recording medium into and out of the housing; at least one radiation conversion device disposed in the housing and configured to attenuate first radiation incident to the apparatus such that at least some of the first radiation, when present, is converted by the at least one radiation conversion device to provide second radiation, the second radiation having a lower energy than the first radiation, wherein the at least one radiation conversion device includes an essentially flat surface for contact with the flat surface of the at least one image recording medium; characterised by: at least one movable element adapted to receive an image recording medium, the at least one movable element being movably disposed in the housing between a loading position, which enables transfer of the at least one image recording medium into and out of the housing via the opening, and a set position, in which the flat surface of the at least one image recording medium, is placed in a position of alignment with the at least one radiation conversion device such that at least some of the second radiation impinges on the at least one image recording medium; the apparatus further including at least one positioning mechanism (14, 17) for the at least one element, the at least one positioning mechanism being adapted to facilitate a movement of the at least one movable element simultaneously in a first direction parallel to the essentially flat surfaces of the at least one radiation conversion device and the at least one image recording medium and a second direction perpendicular thereto. a substantially flat housing including two essentially parallel sides having similar dimensions, the housing further including a plurality of relatively smaller-dimensioned edges, at least one edge of the housing including an opening configured to allow passage of the at least one image recording medium into and out of the housing; at least one radiation conversion device disposed in the housing and configured to attenuate first radiation incident to the apparatus such that at least some of the first radiation, when present, is converted by the at least one radiation conversion device to provide second radiation, the second radiation having a lower energy than the first radiation, wherein the at least one radiation conversion device includes an essentially flat surface for contact with the flat surface of the at least one image recording medium; characterised by: at least one movable element adapted to receive an image recording medium, the at least one movable element being movably disposed in the housing between a loading position, which enables transfer of the at least one image recording medium into and out of the housing via the opening, and a set position, in which the flat surface of the at least one image recording medium, is placed in a position of alignment with the at least one radiation conversion device such that at least some of the second radiation impinges on the at least one image recording medium; the apparatus further including at least one positioning mechanism (14, 17) for the at least one element, the at least one positioning mechanism being adapted to facilitate a movement of the at least one movable element simultaneously in a first direction parallel to the essentially flat surfaces of the at least one radiation conversion device and the at least one image recording medium and a second direction perpendicular thereto.
