中等的热剂量，单独的，造成没有可测量的反应，在软骨的尾巴的幼鼠，可能会加强影响的X射线照射。增强的幅度（热增强比，或TER）取决于热剂量，其方式与在其他正常组织中观察到的方式类似。大鼠尾部的热增强也依赖于X射线的剂量，随着剂量的增加而增加。增强总是更大时，加热前照射，虽然在TER之间的差异加热前或照射后立即小于10%。随着加热和X射线处理的时间间隔的增加，X射线损伤的增强稳定地下降到零。当在加热前给予X射线时，增强作用的丧失更完全和更迅速，但也取决于加热的程度和X射线的剂量。
Moderate heat doses which, alone, cause no measurable response in the cartilage of the tail of the baby rat, may potentiate the effects of X-irradiation. The magnitude of the enhancement (the Thermal Enhancement Ratio, or TER) depends upon the heat dose in a similar way to that observed in other normal tissues. The thermal enhancement in the rat tail was also dependent on the dose of X rays, increasing with increasing dose. Potentiation was always greater when heat was applied before irradiation although the difference in TER between heating immediately before or after irradiation was less than 10%. Potentiation of X ray damage decreased steadily to zero as the heat and X-ray treatments were separated by increasing intervals of time. The loss of potentiation was more complete and more rapid when X rays were given before heating, but was also dependent on both the degree of heating and the dose of X rays.
