Behaviour of thermoluminescence green and red emission bands of natural dolomite irradiated with gamma rays
The green and red emission bands of natural dolomite were analyzed by the thermoluminescence (TL) method to test the possibility of their use in different applications in radiation measurements in a range of doses between 1 Gy and 104 Gy. The natural sample revealed two peaks at 240 °C and 325 °C in...

| description | The green and red emission bands of natural dolomite were analyzed by the thermoluminescence (TL) method to test the possibility of their use in different applications in radiation measurements in a range of doses between 1 Gy and 104 Gy. The natural sample revealed two peaks at 240 °C and 325 °C in the green region and four peaks at 225 °C, 240 °C, 270 °C and 325 °C in the red region. The dose response curves are sublinear for both bands over the range 1–100 Gy and linear over the region 200 Gy to 104 Gy. After γ-irradiation and storage for one month in the darkness at ambient temperature, the remnant TL level was determined to be 39% and 86% in the green and red bands, respectively. |
