Definitions

  • the present invention relates to scintillating crystals, a manufacturing process for obtaining them and the use of said crystals, in particular in detectors for gamma rays and / or X-rays.
  • Scintillator crystals are widely used in detectors for gamma rays, X-rays, cosmic rays and particles whose energy is around 1 KeV and also above this value.
  • a scintillator crystal is a transparent crystal in the scintillation wavelength range, which responds to incident radiation by the emission of a light pulse.
  • detectors can be made in which the light emitted by the crystal which the detector comprises, is coupled to a light detection means and produces an electrical signal proportional to the number of light pulses received and to their intensity.
  • detectors are used in particular in industry for thickness or grammage measurements, in the fields of nuclear medicine, physics, chemistry, petroleum research.
  • a family of scintillating crystals known and widely used is of the sodium iodide type doped with Thallium, Nal (Tl). This scintillator material discovered in 1948 by Robert Hofstadter and which is the basis of modern scintillators still remains the predominant material in this area despite almost
  • a material also used is Csl, which depending on the applications can be used pure, or doped either with Thalium (Tl) or with Sodium (Na).
  • BGO Bismuth Germanate type
  • the energy resolution of a nuclear radiation detector indeed determines its ability to separate very similar radiation energies. It is usually determined for a given detector at a given energy, like the width at half height of the peak considered on an energy spectrum obtained from this detector, related to the energy at the centroid of the peak (see in particular: G. F Knoll, "Radiation Detection and Measurements", John Wiley and Sons, Inc, 2 nd edition, p 114). In the following text, and for all the measurements carried out, the resolution is determined at 662 keV, energy of the main gamma emission of 137 Cs.
  • An increase in the resolution in energy is particularly advantageous for a medical imaging device for example of the Gamma camera type of Anger or Positron Emission Tomograph (TEP), because it makes it possible to greatly improve the contrast and the quality of the images. , thus allowing a more precise and earlier detection of tumors.
  • TEP Positron Emission Tomograph
  • Another very important parameter is the scintillation decay time constant (called “decay time”), this parameter is usually measured by the method called “Start Stop” or “Multi hit method”, (described by WW Moses (Nucl Instr and Meth. A336 (1993) 253).
  • the lowest possible decay time constant is desired, so that the operating frequency of the detectors. In the field of nuclear medical imaging, this allows for example to considerably reduce the duration of examinations.
  • a low decay time constant also makes it possible to improve the temporal resolution of the devices detecting events in temporal coincidence. This is the case with Positron Emission Tomographs (TEP), where the reduction of the decay time constant of the scintillator makes it possible to significantly improve the images by rejecting non-coincident events with more precision.
  • TEP Positron Emission Tomographs
  • the quality of a scintillator is essentially determined by the properties of the contribution of the fastest emission component.
  • the object of the present application relates to a material capable of simultaneously presenting a good resolution in energy, in particular at least as good as that of Nal (TI), a constant of weak decay time, in particular at least equivalent to that of LSO (Ce), and whose intensity of the rapid scintillation component is suitable for the production of high-performance detectors, in particular is greater than 4000 ph / MeV (photon by MeV), or even even greater than 8000 ph / MeV (photon by MeV ).

These materials simultaneously exhibit excellent energy resolution at 662 keV, in particular less than 5%, and even less than 4%. These properties are all the more remarkable since they are unexpected and demonstrate a large discontinuity of characteristics from 1 mole% of cerium.
  • cerium-doped scintillators having good performance such as LSO contain less than 1% of Cerium, and preferably approximately 0.2%.
