The present invention generally relates to a radiation sensor for use particularly in, but by no means exclusively, in measuring radiation dose in photon or electron fields such as for radiation medicine, including radiotherapy and radiation based diagnosis. According to the present invention, there is provided a semiconductor radiation detector comprising a radiation sensitive detector element arranged such that it forms a continuous radiation sensitive portion having surfaces oriented in at least two non-parallel directions.

There is provided an x-ray scintillator () including a pore matrix having a plurality of pores formed in a substrate (). Each of the pores is at least partially covered with a multi-layered coating including at least a reflective layer () and a protective layer (). The at least partially coated pores are filled with scintillating material () for absorbing x-ray photons to produce secondary photons, preferably with a wavelength in the visible range. The reflective layer () of the multi-layered coating is arranged between the scintillating material () and the substrate () for reflecting the secondary photons, and the protective layer () of the multi-layered coating is arranged between the reflective layer () and the scintillating material () for protecting the reflective layer while allowing reflection of the secondary photons by the reflective layer.
