[ 1 ] - سنتز نانوذرات منیزیم سولفات آلاییده شده با مس به روش هیدروترمال و بررسی خاصیت ترمولومینسانس آن‌ها در پرتودهی گاما
In this research MgSO4:Cu nanoparticles was synthesized for the first time by hydrothermal method. The size of the produced nanoparticles calculated by scherrer equation was about 36 nm using XRD pattern which was in agreement with that of SEM analysis. Thermoluminescence (TL) properties of the MgSO4:Cu nanoparticles was investigated in gamma irradiation by 60Co source. Optimum amount of impuri...
[ 2 ] - تعیین پارامترهای فروکشی دمایی دزیمتر ترمولومینسانس (TLD-100) LiF:Mg,Ti
Thermal quenching is a known and important effect which should be taken into account in studying thermoluminescence (TL) phenomenon. This effect causes the probability of non-radiative recombinations to be increased with raising temperature in TL process. This article deals with changes of the TL glow curve of LiF:Mg, Ti (TLD-100) with heating rate. It was observed that the main dosimetry peak ...

[ 4 ] - Recovery of thermoluminescence sensitivity in CaF2:Mn (TLD-400) dosimeter under heating process
In order to recovery the thermoluminescence (TL) sensitivity of CaF2:Mn (TLD-400) thermoluminescent dosimeter it was exposed to high gamma radiation dose of 10kGy, then by applying standard annealing followed by irradiation to 1Gy gamma dose, the TL signal was recorded . The TL response reduced due to the damage effect of high dose irradiation in comparison with control dosimeter with received ...
