It is worth to continuous and systematic investigations related with magnesium tetraborate (MBO) due to its attractive candidate for dosimetric application. The study was done to develop new phosphor with adding strontium (Sr) into MBO which was prepared by the simple high temperature solid state method. Its main dosimetric properties, like glow curve structure, dose response, trapping parameters and fading, were investigated for the first time in the literature. The experimental results indicated that Sr doped MBO ensured essential characteristics for applicability in medical dosimetry, except for the fading (45% lost in 7 days) feature. It had main glow peak with highest intensity at nearly 200 °C with good linearity of the dose-response up to 1150 Gy. This study suggests that Sr-doped MBO is a promising material for dosimetric application, just need to solve the fading problem with addition of another activators as a co-dopant.
