Abstract
Lyoluminescence (LL) is a good technique for radiation dosimetry of high-energy radiations. Dosimetry of γ rays from 60Co radioactive source has been done using MgB4O7:Mn2+ phosphor material. It was synthesized by simple solid state diffusion method. The material shows good linear LL response with the γ rays for the dose rage of 10 Gy–10 kGy. The studies have also been done for different particle sizes (250–45 µm) and particles having average size ~85 µm were found to be the most suitable for this dosimetry. Effect of solvent pH on LL and fading on storage has also been studied.
