1 Geant 4 to simulate Photoelectric , Compton , and Pair production Events
نویسنده
چکیده
An Aluminum (Al) target of 20cm was used in this simulation to see the eect of incoming photons at lower and higher energies ranging from 10eV −1GeV . A photoelectron is produced when a single electron in the metal completely absorbs a single photon. The kinetic energy with which the photoelectron is emitted from the metal is equal to the photon energy minus an energy that the electron expends in escaping the surface [1]. Geant4 simulation gives pretty good approximation if G4LowEnergyPhotoElectric function is implemented to see photo-peaks.

Exposure buildup factors for water and lead have been calculated by the Monte-Carlo method for an isotropic point source in an infinite homogeneous medium, using the latest cross secions available on the Internet. The types of interactions considered are ,photoelectric effect, incoherent (or bound-electron Compton). Scattering, coherent (or Rayleigh) scattering and pair production. Fluorescen...
متن کاملSimple empirical correction functions to cross sections of the photoelectric effect, Compton scattering, pair and triplet production for carbon radiation shields for intermediate and high photon energies
The general review of cross section formulas for the photoelectric effect, Compton scattering, pair and triplet production is presented in the intermediate and high photon energy spectrum for carbon (Z=6). Using the classical Gaussian regressionmethod, the empirical correction functions for the theoretical cross section formulas are calculated based on the existing experimental data. The simp...
متن کاملPair Production and Radiation Effects in Clouds Illuminated by Gamma Ray Sources
Many classes of gamma-ray sources, such as gammaray bursts, blazars, Seyfert galaxies, and galactic black hole sources are surrounded by large amounts of gas and dust. X-rays and gamma-rays that traverse this material will be attenuated by Compton scattering and photoelectric absorption. One signature of an intervening scattering cloud is radiationhardening by electrons that have been scattered...

متن کاملAn iterative method to estimate x-ray attenuation coefficients in computed tomography
Introduction: The basis of image formation in Computed Tomography (CT) lies in the x-ray linear attenuation coefficient of the scanned material. Compton scattering and photoelectric effect are the dominant interactions of the x-ray photons with the subject, in the range of diagnostic radiology. These two coefficients are important in tissue characterization by Dual-Energy CT (D...
