Overview

Monte Carlo simulations revealed energy spectra differences impacting dosimetry in various dose-measuring devices.

Key Points

  • Average photon energy was observed to change significantly with depth for both 6 MV and 10 MV beams.
  • Energy spectra differences were calculated using Monte Carlo simulations, showing relevance for dosimetry applications.
  • Dosimetry analysis was performed with various dosimeters, including ion chambers, TLDs, and OSLDs, under reference and magna field conditions.
  • These findings highlight the need for accurate dosimetry protocols when using magna fields in clinical settings.
