| description | The utility model relates to a fingernail in-vivo paramagnetic resonance measuring probe device for radiation dose measurement. The fingernail in-vivo paramagnetic resonance measuring probe device comprises a resonant cavity, a tuner, a coupling structure and a tuning bolt, the surface of the resonant cavity is provided with a narrow slit sample detection port, the resonant cavity is connected with a tuner, and the tuner is connected to a microwave bridge through a waveguide. A microwave coupling structure is arranged in the tuner, and the coupling coefficient of the coupling structure is adjusted through a tuning bolt. The in-vivo electron paramagnetic resonance detection device can be used for directly carrying out in-vivo electron paramagnetic resonance detection on fingernails so as to evaluate the radiation dose of personnel, so that the problem of mechanical induction signal interference in the conventional in-vitro fingernail measurement is solved, and the accuracy of dose evaluation is improved.
