Description
A highly sensitive and nearly tissue equivalent LiF:Mg,Cu,P Thermoluminescent (TL) phosphor in powder form has been developed for its use in Personnel Monitoring and Radiation Dosimetry in medical field. The TL sensitivity of indigenously prepared LiF:Mg,Cu,P(0.4, 0.002, 0.85 mol%) phosphor is about 1.5 times that of Harshaw-Bicron LiF:Mg,Cu,P (TLD-100 H) by peak height measurements. It gives TL emission band around 370 nm. Its dose -vs-TL response is linear up to 10 Gy Annealing temperature was found to affect the glow curve shape and sensitivity. Reusability study at 240 deg C shows that its sensitivity does not decrease even after 10 cycles of reuse. (author)
