• The maximum intensity of LiF:Mg,Cu,P annealed at 460 °C occurred at 280 °C.
• LiF:Mg,Cu,P with a maximum intensity at 280 °C should present good thermal stability.
• The LiF:Mg,Cu,P should have a minimum measurable dose in the range of micro-Gy.
• The LiF:Mg,Cu,P could be re-used with re-annealing at 660 °C + 270 °C + 240 °C + 460 °C.
• LiF:Mg,Cu,P could be used for low dose test in an environment with elevated temperature.
Efforts are aimed at finding a method that could serve TL dosimetric measurements in the range of low-dose but carried out in an environment with elevated temperature. The temperature at the position of the maximum intensity of LiF:Mg,Cu,P was about 280 °C when annealed at 460 °C. LiF:Mg,Cu,P with a maximum intensity at 280 °C should present good thermal stability. The TL intensity of LiF:Mg,Cu,P with a maximum intensity at 280 °C was about 54% of the standard LiF:Mg,Cu,P, it should have a minimum measurable dose in the range of micro-Gy. LiF:Mg,Cu,P with a maximum intensity at 280 °C could be re-used by the 660 °C/30 min annealing, followed by 270 °C/20 min, 240 °C/10 min and 460 °C/30 min. It's possible for LiF:Mg,Cu,P to be extended application for low dose test in an environment with elevated temperature.
