ENDOR and ENDOR-induced-EPR techniques were applied to a study of radiation defects in human tooth enamel. Matrix ENDOR signal was observed correspondent to minimal distances from paramagnetic center to 1H nuclei of 5.5 A and 31P that of 6 A. A hole in 1H ENDOR spectrum taken from the left wing of EPR line appears at high dose, which was tentatively ascribed to a part of traps with disturbed spatial properties by surrounding radiation defects.
电子核双共振(ENDOR)和ENDOR诱导电子顺磁共振(EPR)技术被应用于研究人类牙釉质中的辐射缺陷。观察到基质ENDOR信号对应于顺磁中心到1H核的最小距离为5.5埃,到31P核的最小距离为6埃。从EPR线左翼获取的1H ENDOR谱在高剂量时出现一个峰,初步认为这归因于一部分因周围辐射缺陷而空间性质受到干扰的陷阱。
