ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. 'Dose-response' dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of 'radiosensitivity' enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.
电子自旋共振光谱法被用于研究哺乳动物（食肉动物（北极熊和狐狸）、有蹄类动物（驯鹿、欧洲野牛、驼鹿）以及人类）牙齿釉质中辐射诱导的顺磁中心。在室温下评估的辐射信号微波功率饱和值的一半（P1/2），对于动物和人类而言，其范围为16至26毫瓦。提出了一种从驯鹿牙齿釉质的总电子自旋共振光谱中区分辐射诱导信号的新方法。在0.48至10.08戈瑞的剂量范围内，测量了不同种类哺乳动物牙齿釉质的“剂量-反应”依赖性。通过电子自旋共振法对食肉动物和有蹄类动物牙齿釉质“辐射敏感性”的估计与人类牙齿釉质的辐射敏感性显示出良好的一致性。
