Abstract
Electron spin resonance (ESR) tooth spectroscopy offers the possibility of in vivo dosimetry for radiation accident emergency. We developed an X-band ESR cavity for in vivo measurement of tooth enamel, which is a cylindrical cavity working at TE111 mode. A narrow rectangular aperture to fix incisors was opened on the cavity wall, where there were strong microwave magnetic field component H1 and weak microwave electronic field component E1 inside the cavity. The external modulated magnetic field was applied to the incisors from both sides of the aperture. Theoretical calculations and simulations were discussed to optimize the characteristics and predict the cavity working conditions and performances. The characteristics were evaluated by measuring DPPH and whole incisor samples. Remarkable radiation induced signal of 2Gy irradiated tooth could be obtained by one 5-min ESR spectroscopy. This result indicated that the cavity was sensitive enough to detect the radiation-induced signal in human teeth. This paper describes the operation principle, configuration, and characteristics, and reports the DPPH and tooth experiments to verify the cavity.
