The efficiency versus energy curve of the detector was determined experimentally using standard gamma-ray point sources with known strength, 152Eu, 133Ba, 241Am. 60Co and 137Cs. Efficiency is also calculated using the EGS4 Monte Carlo Code [Nelson et al, 1985]. */ /* Experimental Method: - Stacked target irradiation (Stack was assembled from molybdenum, copper and aluminium as Cu-Al-Mo and 10 groups were set together in an aluminium holder for irradiation.) - Energy degradation by foils (Energy degradation along the stack was determined using the computer program SRIM-2002 [J.F. Ziegler et al., The stopping and range of ions in solids, Pergamon, New York, 1984.] assuming the incident energy was 70 MeV.) /* Analysis: - Decay curve analysis (Two or more radionuclides emitted gamma-rays having very close energies, which were difficult to separate by the graphical analysis of the multicomponent decay curve, were analyzed using the difference in half-life of the nuclides by plotting the photon emission rate as a function of time.) /* Gamma energies given (except 90Tc and 90Nb) are obtained by private communication with authors. */ /* Related references - V.N.Levkovskij, LEVKOVSKIJ, (1991).
