Title (EN) METHOD FOR DETECTING RADIATION DOSE UTILIZING THERMOLUMINESCENT MATERIAL
(FR) PROCEDE DE DETECTION DE DOSE DE RADIATION UTILISANT UNE MATIERE THERMOLUMINESCENTE
Abstract:
(EN) The amount of ionizing radiation to which a thermoluminescent material has been exposed is determined by first cooling the thermoluminescent material to a cryogenic temperature. The thermoluminescent material is then optically stimulated by exposure to ultraviolet light. Visible light emitted by the thermoluminescent material as it is allowed to warm up to room temperature is detected and counted. The thermoluminescent material may be annealed by exposure to ultraviolet light.
(FR) On détermine la quantité de radiation ionisante à laquelle la matière thermoluminescente a été exposée, premièrement, par refroidissement de la matière thermoluminescente à une température cryogénique. Ensuite, on stimule optiquement ladite matière thermoluminescente par exposition à la lumière ultraviolette. On compte et on détecte la lumière visible émise par ladite matière thermoluminescente à mesure qu'on la laisse se réchauffer à température ambiante. On peut soumettre à un recuit ladite matière thermoluminescente par exposition à la lumière ultraviolette.
