International audience; This communication reports the very first experimental results on an original wireless, chipless and passive (battery-less) sensor for monitoring high doses of nuclear radiation. The micro-sensor combines a miniature hydrogen pressure dosimeter with a passive microwave resonator. The pressure response is derived from S11-parameter measurement using vacuum and atmospheric pressure conditions. After e-beam irradiation (20kGy) the resonant frequency shift of the resonator ranges between 0.12%/kGy and 0.42%/kGy while the hydrogen pressure inside the cavity varies from 20mbar/kGy to 90mbar/kGy. No significant frequency shift is observed when using sensors during 6 months. These results demonstrate that a good hydrogen hermetic seal was fabricated during the manufacturing process of the constitutive micro-cavity.
