1. A method for generating a response function of a scintillator to incident gamma rays of energy within a range of energies of interest, the method comprising:
(a) obtaining the responses {Si} of the scintillator to a plurality of known radionuclides i (i=1, . . . N), each radionuclide i emitting gamma rays with known energetic properties (Eij, Yij),
(b) decomposing, for each radionuclide i, the response Si into primary responses of the scintillator Sij=ƒ(λij, Yij, Xij), each primary response corresponding to the response of the scintillator to a received gamma ray of a known energy Eij for this radionuclide i,
(c) deriving from the primary responses {Sij} the response function ƒ(λ, X) of the scintillator to an incident gamma ray of any energy E within the range of energies of interest.
