چکیده مقاله:
In this research, alumina nanoparticles were prepared by a sol-gel method, and characterized via X-ray diffraction (XRD) and scanning electron microscope (SEM) to understand the structure, size, and shape of particles. In addition, the thermoluminescence radiation curve of these nanoparticles, irradiated with gamma rays from the ۶۰Co source, was fitted with a computer program and their trapping parameters were calculated numerically. Two overlapping peaks at temperatures of ۴۴۳ and ۴۶۱ K were observed in the thermoluminescence curve of the nanoparticles. The obtained results show that the alumina nanoparticles are suitable for use in dosimetry.
