The paper presents the thermoluminescence (TL) response of strontium tetraborate glass subjected to electron irradiations at various Dy2O3 concentrations ranging from 0.00 to 1.00 mol%. All glass samples exhibited single broad peak with maximum peak temperature positioned at 170–215 °C. The optimum TL response was found at Dy2O3 concentration 0.75 mol%. This glass showed good linearity and higher sensitivity for 7 MeV compared to 6 MeV electrons. Analysis of kinetic parameters showed that the glasses demonstrate second order kinetic.
