Some dosimetric properties of the glass system 50P 2 O 5 •30-40CaO•20-10Na 2 O mol% were studied applying the thermoluminescence technique.. The glass samples were powdered, and were pressed with Teflon™ in the proportion 1:2 to produce pellets. The glow curves of the pellets presented three peaks at 130 °C, 215 °C and 270 °C, respectively. The TL response reproducibility presented a maximum coefficient of variation lower than 10%. The calibration curve is linear between 1.0 Gy and 1 kGy. Minimum detection limits were also determined. The gamma radiation dose response and the thermal stability of the materials were studied with the purpose to establish the best conditions of the present bioglass system for use in gamma ray TL dosimetry.
