Monte Carlo simulation for bremsstrahlung and photoneutron yields in high-energy x-ray radiography

doi:10.1088/1674-1056/19/6/062901

Abstract This paper reports on the results of calculations using a Monte Carlo code (MCNP5) to study the properties of photons, electrons and photoneutrons obtained in the converted target and their transportations in x-ray radiography. A comparison between measurements and calculations for bremsstrahlung and photoneutrons is presented. The radiographic rule and the effect of the collimator on the image are studied with the experimental model. The results provide exact parameters for the optimal design of radiographic layout and shielding systems.

Keywords: x-ray radiography bremsstrahlung photoneutron energy spectrum angular distribution
