The invention discloses a multiple NaI (T1) detectors based radioactive substance two-dimensional locating method in an access control detection system. A two-dimensional locating model of a radioactive substance is determined through the measurement of the attenuation law of gamma rays and the change of the azimuth angle of the radioactive substance at different positions relative to a detector. The energy resolution capability of the NaI detector is utilized to recognize the radioactive nuclide, and the problems of mutual interference of different radioactive nuclides and simultaneous location of different radioactive substances can be effectively solved under a multi-source condition. According to the method, a maximum characteristic peak counting detector with high counting capability, a detector at the opposite side and a second largest characteristic peak counting detector at the opposite side are adopted, situations that the location error is increased and even a position close to the edge cannot be located due to the influence of statistical fluctuation on the counting value of the detector when the solid angle of the radioactive substance on the detection surface of the detector is too small or the attenuation distance is overlong are avoided, and the method has the advantages of short measurement time, high location accuracy and the like.
