The thermoluminescence technique is widely used for both personal and high-dose dosimetry. In this work, the thermo-luminescence technique was employed to study a new glass matrix, with nominal composition of 20Li2CO3.10Al2O3.30BaO.40B2O3 (mol%), irradiated with different doses in a 60Co radioactive source. The glow curves and the dose-response curve were obtained for radiation doses of 10, 50, 100, 200 and 700 Gy. The results showed that this new glass matrix has potential use in high-dose dosimetry.
Evaluation of glasses containing cadmium for high dose dosimetry by the thermoluminescence technique
2017 - CARVALHO, G.S.M.; FERREIRA, P.Z.; DANTAS, N.O.; SILVA, A.C.A.; PERINI, A.P.; CALDAS, L.V.E.; CARRERA, B.N.S.; WATANABE, S.; NEVES, L.P.
New glass matrices were evaluated for high dose dosimetry by the thermoluminescence technique. Their nominal com-position are 20Li2CO3.10Al2O3.15CdO.55B2O3 and 20Li2CO3.10Al2O3.20CdO.50B2O3 (mol%). The glass matrices were irradiated with different doses: 50, 100, 200, 500, 700 and 900 Gy, and the thermoluminescence emission curves were obtained for each of these values. The results show a great potential of using these matrices in high dose dosime-try.
