BORATE SILICA GLASS SYSTEM DOPED WITH SODIUM AS A DOSIMETRIC MATERIAL SUBJECTED TO ELECTRON AND PHOTON BEAM

Varies concentration of Sodium doped borate silica glasses are studied in term of thermoluminescence properties to find their option to use as glass radiation dosimeter. The optimum samples 44.9ZnO-45B2O3-10SiO2- 0.1Na2O were exposed to 6 MeV, 6 MV and 10 MV photon beams in a dose range of 0.5–4.0 Gy. There is a single and broad thermoluminescence glow curve that exhibits its maximum intensity at about 160 °C. Linear dose response behavior has been found in this dose range for the both electron and photon beam. The sensitivity of 44.9ZnO-45B2O3- 10SiO2- 0.1Na2O glass sample is 1145.87 (nC.Gy-1 .g-1 ) and 1224.46 (nC.Gy-1 .g-1 ) for 6MeV and 6MV. The results indicate that this glass has a potential to be used as a radiation dosimetry.
