PCT No. PCT/FR92/00118 Sec. 371 Date Dec. 10, 1992 Sec. 102(e) Date Dec. 10, 1992 PCT Filed Feb. 11, 1992 PCT Pub. No. WO92/13492 PCT Pub. Date Aug. 20, 1992.Ionizing radiation sensors, such as X-ray or Gamma-ray sensors, used in industrial or medical radiology imaging systems. The sensor (1) employs a charge-coupled device (20) coupled to a scintillator element (51) and a filter for impeding the passage of ionizing radiation not transformed by the scintillator element (51). The filter is formed by the combination of a non-optical element which consists of a group of tubular guides (40), wholly or partly metallic, and the scintillator element (51) which consists of a scintillator material charged with absorbant particles (52). The scintillator element (51) is housed in the non-optical element (40). The sensor (1) is particularly usable in the field of intra-oral dental radiology.
