摘要: Abstract In this study, thermoluminescence (TL) properties of the calcite extracted from natural sand which is used in making roasted chickpeas were investigated. And also effects different thermal treatments on glow curve observed. Two distinct TL peaks observed at ~130 °C and ~230 °C. The annealing sample, especially 900 °C, causes a huge enhancement sensitization TL. Linearity dose response for values up to 0.6 kGy above linearity not preserved becomes sublinear. best reproducibility obtained when samples are annealed between 400°C 600 °C.
