The thermoluminescence of the 200 and 260 degrees C peaks of 7LiF has been measured and compared with off-axis dose and depth-dose distributions for three therapeutic high-LET beams: negative pions, helium ions and neon ions. The methods of analysis consisted of both a single-peak analysis and the dual-peak analysis methods of Hogstrom and Irifune and Hoffmann et al. The results indicate that 7LiF, analysed by the dual-peak analysis methods, is potentially useful for extracting total dose, high-LET dose, and beam quality of helium-ion and negative-pion beams. For the higher-LET neon beam, differences in sensitivity between the 200 and 260 degrees C peaks of 7LiF were found to be independent of variations in LET within the beam; consequently, only the single-peak analysis method is applicable in which case the dosemeter at best can only estimate total dose.
已测量了7LiF在200℃和260℃峰值处的热释光，并将其与三种治疗性高传能线密度（LET）束流（负π介子、氦离子和氖离子）的离轴剂量和深度剂量分布进行了比较。分析方法包括单峰分析法以及霍格斯特伦、入船和霍夫曼等人的双峰分析法。结果表明，采用双峰分析法分析的7LiF对于提取氦离子束和负π介子束的总剂量、高LET剂量和束流质量具有潜在的用途。对于较高LET的氖束，发现7LiF在200℃和260℃峰值处的灵敏度差异与束流内LET的变化无关；因此，仅适用于单峰分析法，在这种情况下剂量计最多只能估计总剂量。
