A method was proposed to transfer the efficiency of gamma-ray spectrometers calibrated with a standard water source to suit other samples. In our method, it is not important to know the concentration of the major elements of the sample to be measured. This gives a special importance to our method for low-energy photon detection where the self-absorption is strongly material dependent.
