Monte Carlo simulation-based gamma energy spectrum generation method, storage medium and system

The invention relates to a Monte Carlo simulation-based gamma energy spectrum generation method, which comprises the following steps of: defining a gamma ray transport space as a cube, cutting the cube into a plurality of equal small blocks, and filling a predetermined material in the plurality of equal small blocks according to a relative probability value; geometric arrangement of the detector is carried out, and the detector geometry is represented by a cylinder; performing gamma energy spectrum broadening setting; determining the type of gamma rays, and defining the number and position of source particles; the invention also provides a storage medium and a Gamma energy spectrum generation system based on Monte Carlo simulation, and the Gamma energy spectrum generation method based on Monte Carlo simulation, the storage medium and the system can generate a large number of high-simulation general Gamma energy spectrum samples. The generated sample can cover the real morphological characteristics of the ener
