Monochromator harmonic content measurements and calculations at energies above 20 keV

Bremsstrahlung Cross Sections in Ceramic Compounds at Incident Electron Energies (10 kev, 20 kev and 30kev)

Numerical bremsstrahlung cross sections for different ceramic compounds like Alumina (Al2O3), beryllia (BeO), ceria (CeO), Zirconia (ZrO2) were calculated by using Zmod of metallic compounds at different incident electron energies (10 keV,20 keV and 30 keV) in the photon energy regions of energy (1-10 keV,1-20 keV and 1-30 keV). The cross sections were calculated by using Elwert corrected (non ...

Comparison of GATE/GEANT4 with EGSnrc and MCNP for electron dose calculations at energies between 15 keV and 20 MeV.

The GATE Monte Carlo simulation platform based on the GEANT4 toolkit has come into widespread use for simulating positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging devices. Here, we explore its use for calculating electron dose distributions in water. Mono-energetic electron dose point kernels and pencil beam kernels in water are calculated for dif...

Potential Harmonic Calculations of theBinding Energies of

RBE of Neutrons at Energies of 36 keV-15 MeV and Photons at Energies of 1

We examined the induction of dicentrics in human lymphocytes irradiated in vitro with nearly monoenergetic neutrons at energies in the range of 36 keV-15.0 MeV and monochromatic X-rays in the range of 1.8 keV-40 keV. For the assessment of the relative biological effectiveness (RBE) both 220 kV X-rays and Co γ-rays were used as reference radiations. To avoid potential confounding factors that wo...

Atmospheric proton and neutron spectra at energies above 1 GeV

We discuss an effective numerical method for solving the transport equations for cosmic ray nucleons in the atmosphere. It is demonstrated that the nucleon attenuation lengths are strongly energy and depth dependent due to the non-power-law behavior of the primary spectrum, growth of the total inelastic cross sections with energy, and scaling violation in the nucleon-nucleus interactions. The n...
