Abstract:
1. A method for determining the presence of a material composition in a material sample, said material sample emitting radiation, comprising: recording a spectrum of the energy deposited in a detector material by the emitted radiation; determining a first deposited energy as an integral of the recorded energy deposited over a first energy range extending from a first energy to a second energy, determining a second deposited energy as an integral of the recorded energy deposited over a second energy range extending from the second energy to a third energy, and determining a third deposited energy as an integral of the recorded energy deposited over a third energy range; assigning a first colour parameter to the first deposited energy, a second colour parameter to the second deposited energy, and a third colour parameter to the third deposited energy; determining a colour vector from the first colour parameter, the second colour parameter and the third colour parameter; and comparing the colour vector with a volume in a three-dimensional colour parameter space associated with a predetermined material composition so as to determine if the material sample includes the predetermined material composition.
