ABSTRACT:
The disclosure concerns a pellet type LiF element for a thermoluminescent dosimetry (TLD) and its preparation. More particularly, the disclosure concerns the pellet type LiF element for a thermoluminescent dosimetry (TLD) which includes 0.35˜0.12% by mole of Mg source; 0.08˜0.001% by mole of Cu source; 1.3˜0.5% by mole of Na source; and 1.3˜0.5% by mole of Si source as dopants. The pellet type LiF element according to the present invention shows excellent sensitivity and has the preferred glow curve with a simple and single main peak.
