(EP960442-A1)       The production of a radiation detector, consisting of a scintillator and a photosensitive structure of spaced panel units (10a , b ) with active elements or pixels (RMa , b ), involves placing the panel units alongside one another at a predetermined spacing (e) on a positioning substrate (8) to form a large composite panel, in which the active elements or pixels (RMa , b) face the substrate, and then bonding the composite panel onto a common support (7).     The novelty is that the bonding operation comprises: (a) filling the inter-panel spaces (e) with an adhesive bead (6') leaving a free zone between its lower end and the positioning substrate (8); and then (b) spreading an adhesive film (6") over the panel units (10a , b) and the bead (6').    Also claimed is a radiographic detector produced by the above process.    USE -   Used for producing a large solid state x-radiation detector panel useful in radiology.    ADVANTAGE -   The process retains the advantages of prior art bonding processes (especially optical transparency, mechanical flexibility and optionally thermal properties), while the bead adhesive prevents migration of the less viscous film adhesive and thus avoids degradation of the cleanness and topography of the faces onto which the scintillator material is to be deposited.
