1. A method for characterizing a property characteristic of a transmission source of a segmented γ scanning measurement system, comprising:
step A02. manufacturing a plurality of standard transmission objects for the segmented γ scanning measurement system;
step A04. simulating and calculating a transmission measurement process, based on the plurality of standard transmission objects, so as to establish a database with respect to a transmission thickness of each standard transmission object of the plurality of standard transmission objects, an equivalent water density of each standard transmission object, an original reconstruction density of each standard transmission object, a source distance of each standard transmission object, an energy of a γ-ray, and a space angle cosine of a transmission source;
step A06. fitting a corresponding relationship of the space angle cosine of the transmission source with respect to the transmission thickness of each standard transmission object, the equivalent water density of each standard transmission object, the original reconstruction density of each standard transmission object, the source distance of each standard transmission object, and the energy of the γ-ray based on the database;
step A08. selecting a corresponding standard transmission object for a transmission measurement according to the transmission source to be characterized, so as to determine the original reconstruction density of the corresponding standard transmission object; and
step A10. characterizing the space angle cosine of the transmission source to be characterized according to the corresponding relationship fitted in the step A06 by using the transmission thickness of the corresponding standard transmission object, the equivalent water density of the corresponding standard transmission object, original reconstruction density of the corresponding standard transmission object, the source distance of the corresponding standard transmission object determined in the step A08, and the energy of the γ-ray emitted by the transmission source to be characterized.
