Embodiments of the invention provide a radiation detector, comprising a convertor comprising an inorganic scintillator for absorbing incident neutrons and outputting photons, a light collecting body arranged in relation to a wavelength shifting fibre for receiving photons from the convertor and directing the photons to the wavelength shifting fibre, and one or more photo-detectors arranged to receive photons from the wavelength shifting fibre and output electrical signals in response thereto. |
