The invention relates to a method of producing a radiation detector comprising a photosensitive receiver (1; 30; 41) associated with a radiation converter (5) which is fixed by bonding to the photosensitive receiver (1; 30; 41). The method uses a film of adhesive (6; 61; 62) protected on each of its faces by a protective film and in carrying out the following operations in succession. A one protective film is removed. The film of adhesive (6; 61; 62) is laminated to the first element (5). The second protective film is removed. The second element (1; 30; 41) is brought into contact with the film of adhesive (6; 61; 62). The invention also relates to a tool for producing a radiation detector and to a method of employing this tool.
