The invention relates to a device for detecting input radiation such as X-rays, γ-rays, ionizing radiation or fluorescent and low-level light. The device has at least one detection element comprising a sensor component (scintillator) for converting the input radiation into photons (scintillation light) in the UV, visible or IR part of the electromagnetic spectrum and an optical amplifier component which receives the light converted by the sensor component, forwards it for further processing and amplifies it at the same time. According to the invention, the amplifier component comprises at least one optical waveguide (1, 2, 2a, 2b, 20) whose material is optically pumped to amplify the scintillation light (3, 24, 25).
A method for the detection of incident -radiation, comprising converting said incident radiation in a sensor section of an optical waveguide into a radiation output comprising photons in the UV, visible, or IR portions of the electromagnetic spectrum by interacting with a photon-emitting material included in a glassy material having crystal-like properties and a sufficient density to stop γ-radiation, and amplifying said radiation output in an optically pumped amplifier section of said optical waveguide, the amplifier section comprising a glassy material having crystal-like characteristics and a sufficient density to stop γ-radiation.
