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.
本研究比较了热释光剂量计（TLD）晶体LiF:Mg,Ti（TLD - 100）和LiF:Mg,Cu,P（TLD - 700H）在临床剂量测定中的相对有效性，重点关注再现性、线性和能量响应。实验结果表明，TLD - 700H在再现性、无超线性以及热释光（TL）信号随辐射质量无变化方面优于TLD - 100。TLD - 700H还具有更高灵敏度和即时可读性的额外优势。研究人员得出结论，这种相对较新的TLD晶体在临床剂量测定中显示出有前景的潜力。
