DESCRIPTION:Speakers: Enoch Sithole (University of Limpopo)\nThe purpose o
 f this work was to study the dose enhancement factor (DEF) by high-Z mater
 ial in water phantom\, irradiated by photon beams. Two energies\, 6 and 15
  MeV generated by Varian linear accelerator were used. Monte Carlo techniq
 ue (EGSnrc code) was used in this study. The source model was validated ag
 ainst measured data. The effect of photon beam quality\, atomic number (Z)
  and the material thickness in the water phantom were studied. Calculation
 s for a variety of materials and photon beams showed that dose enhancement
  factor increase with Z\; decrease with decreasing material thickness\; an
 d decrease with decreasing incident photon beam energy.\n\nhttps://events.
