A study on annealing technique for Lif:Mg,Cu,P thermoluminescent dosimeter
The ineffectiveness of the oven annealing for the LiF:Mg,Cu,P thermoluminescent dosimeter with a thick annealing tray was demonstrated to be due to the fact that the temperature achieved on the annealing tray was significantly lower than the oven preset temperature. The 240 °C/10 min annealing using...

Zusammenfassung: | The ineffectiveness of the oven annealing for the LiF:Mg,Cu,P thermoluminescent dosimeter with a thick annealing tray was demonstrated to be due to the fact that the temperature achieved on the annealing tray was significantly lower than the oven preset temperature. The 240 °C/10 min annealing using a special-designed hot plate, for which the heating temperature on the thin annealing tray can be accurately controlled, has been presented to be capable to reduce the residual signal of the TLD-700H, TLD-7000, and TLD-2007 detectors to less than 0.02% and achieve a reproducibility for 10-cycle measurements of ∼0.36% when an optimal readout cycle has been applied. |
