A method of reducing the Compton distribution from gamma-ray spectra recorded by Nal(Tl) detector using the NE-213 organic scintillator is presented. The similarity of the Compton distributions between both detectors may allow subtracting the NE-213 spectrum from the Nal(Tl) spectrum after making certain calibrations in energy, resolution and count rate at the Compton peak. The method is applied by using the ¹³⁷Cs and ⁶⁰Co gamma-ray standard sources. The "photopeak" spectra obtained showed that the Compton distribution may be highly reduced and the photopeaks are very well isolated
