【Abstract】 In order to solve the problem of X-ray absorbed dose of measuring device in the radiation effect of electronic components, this paper uses Geant4 Monte Carlo program to simulate the absorbed dose of X-ray in water phantom and silicon phantom, and obtain the absorbed dose conversion factor of silicon and water. The calculation results show that under the continuous energy spectrum of X-ray tube voltage of 60 kV, the conversion factor of silicon absorbed dose and water absorbed dose is 6.9290. This result is in good agreement with the calculated result of mass energy absorption coefficient conversion method, indicating that this calculation method is feasible and lays a foundation for the study of X-ray radiation effects of electronic components.更多还原
