Effect of annealing on natural calcitic crystals-A thermostimulated luminescence (TSL) study

►Normally, the synthetic material was used as radiation dosimeter but the natural material can also be used for the same application. ► A wide dose linear response to gamma radiation is observed in the range of 0.5-104 Gy. ► The natural material is not harmful to human body and more eco-friendly so it most suitable for radiation dosimetry.
