Abstract


This work describes the thermoluminescent (TL) characteristics of lithium aluminosilicates, Li$_{2}$OAl$_{2}$O$_{3}$nSiO$_{2}$, for its possible use as TL dosimeter for low doses. The sinterized tablets of Li$_{2}$OAl$_{2}$O$_{3}$nSiO$_{2 }$were characterized by means of X ray diffraction (XRD), and irradiated at different doses using a Theratron 780C-$^{60}$Co unit in air at room temperature. The Rasheedy's technique was used for the kinetic trap parameters determination. The XRD results show a mixture of two phases of 64% $\beta $-spodumene and 36% $\beta $-eucryptite in the sinterized tablets. TL analysis indicates that in these systems, recombination processes prevail, and that these systems can be used successfully as TL dosimeters for therapeutic dose ranges.
