Numerical modeling of radiation treatment of materials

The article gives an example of the application and effectiveness of radiation technologies in various industries. The necessity of using numerical modeling in radiation technologies is determined and justified. The program code based on GEANT4 with the ability to enter complex geometric objects is developed. The developed code based on the GEANT4 software allows modeling of radiation treatment of materials. A corresponding C ++ class was developed for inputting the radiation source into the program code. The results of the calculated absorbed dose rate from experimentally measured are analyzed.
