دراسة تأثير المعالجات الحرارية على الاستجابة و الفقد لمقننات CaF2 : Dy المستخدمة لغرض التقنين الإشعاعي البيئي

الملخص EN

The effect of annealing temperatures on the response and fading for CaF2:Dy crystals used into a thermoluminescence dosimetry has been studied in the present work ,pre and post –irradiation annealing : 1500C /h -100 0C/2h, 2500C /h-1000C /2h ,3500C /h-1000C /2h and 4000C /h-1000C /2h have been studied .The results of the thermal fading and the response of these thermal treatments are : (8.7% , 7.9% , 8% 7%,) ,(107.3 ,117.5,119.5 ,134.2) respectively.

Upon the result obtained ,the pre and post–irradiation annealing with 4000C /h-1000C /2h increases sensitivity and decreases thermal fading, which is of the finest processors thermal compared to the parameters in question.
