The newly developed TE101 mode rectangle EPR cavity is designed for X-band in vivo EPR tooth dosimetry, with a sample detection aperture on its surface. Characteristics were evaluated using DPPH and intact human incisor samples, showing remarkable radiation induced signals from EPR spectrum of teeth irradiated at 1Gy-8Gy. In vivo measurements on rats confirmed its potential application for in vivo tooth dosimetry.
The TE101 mode rectangle EPR cavity was newly developed to achieve X-band in vivo EPR tooth dosimetry for the rescue of nuclear emergency. An aperture for sample detection was opened on the cavity's surface. Its characteristics were evaluated by measuring DPPH and intact human incisor samples. Remarkable radiation induced signal from EPR spectrum of 1Gy-8Gy irradiated teeth was observed. In vivo measurements of rat was performed to verify its application for in vivo tooth dosimetry.
