Radiation induced paramagnetic centers in human tooth enamel as studied by ENDOR.
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.
