Patent ID: 6998632

Claim:
Radiation sensor for dosimetry, comprising: at least one element made out of a radiation detection material, wherein this element has first and second extremities and an axis which passes through these first and second extremities, and the material is configured to emit a luminescence radiation and is transparent to this luminescence radiation; and first and second radiation filter screens, wherein the first screen is placed opposite the first extremity of the element and is configured to filter the radiation that reaches the element along a direction close to the axis of the element, the second screen is thicker than the first screen, and this second screen is placed at the periphery of the element and is configured to filter the radiation that reaches the element along a direction close to a direction that is perpendicular to the axis of the element, wherein this sensor is configured to be optically coupled to a flexible light guide configured to collect and convey the luminescence radiation.
