title: Comparison of effectiveness of thermoluminescent crystals LiF:Mg,Ti, and LiF:Mg,Cu,P for clinical dosimetry.
abstract: This study compared the relative effectiveness of TLD crystals LiF:Mg,Ti (TLD-100) and LiF:Mg,Cu,P (TLD-700H) for clinical dosimetry, focusing on reproducibility, linearity, and energy response. Experimental results indicated that TLD-700H was superior to TLD-100 with regard to reproducibility, lack of supralinearity, and the absence of variation in TL signal with radiation quality. TLD-700H also had the additional advantages of higher sensitivity and immediate readability. The investigators conclude that this relatively new TLD crystal shows promising potential for clinical dosimetry.
