The invention relates to the technical field of passive nuclear material level measurement, in particular to a method for determining a middle material level curve of a continuous passive nuclear material level gage. The method adopts a direct method and comprises the following steps that firstly, the continuous passive nuclear material level gage is arranged in a selected position; then, the material level is determined in other measurement modes, and the intensity of gamma rays corresponding to different material levels are measured in different material levels according to the measurement precision requirement; and finally, the material levels are determined according to the practically measured gamma ray intensity, and a reckoning method or a reference method can also be adopted for replacing the direct method. The method has the advantages that the blanks in the prior art are filled, the method applicable to the continuous passive nuclear material level gage for determining the material level and gamma r
