IDENTIFYING RADIATION USING A PROPORTIONAL GAS COUNTER

摘要

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<1/2> 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.
