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 concluded that this relatively new TLD crystal shows promising potential for clinical dosimetry.
