    • An radiation detector comprises a scintillating layer (3); a radiation entrance (9); and a light detection arrangement (16) including a two-dimensional matrix of light detecting elements (17), wherein the light detection arrangement is oriented with respect to the radiation entrance such that light (25), being emitted in the scintillating layer in a direction essentially perpendicular to the direction at which the radiation beam is entered into the scintillating layer, is detectable. Further, a grid-like layer (13) including a plurality of light-transparent openings (15) is arranged between the scintillating layer and the light detection arrangement and aligned therewith, such that the respective light-transparent openings (15) are overlying the respective light detecting elements (17).

    • A method of identifying radiation detected in a wall-less proportional gas counter providing a stable pulse height spectrum. The method comprises i) transforming the detected pulse height spectrum (dn/dx) in accordance with the transform u=x where x represents the energy of the detected pulses in the original pulse height spectrum; ii) generating a normalised spectrum in u-space comprising a representation of dn/du as a function of u, where n is the detected pulse count as a function of x; iii) deconvoluting the normalised spectrum in u-space to enhance the spectrum; and iv) determining from the enhanced spectrum the energy (or energies) and/or the intensity (or intensities) of the detected radiation.
