Relative dose-response from solid-state and gel dosimeters through Monte Carlo simulations

The present work compared the relative absorbed dose of some dosimetric materials, for energies 250 kV and 6 MV, using PENELOPE MNCPX codes. composition each material GD-301, TLD-100, MAGIC, MAGAT were simulated disposed in a phantom filled with water following reference conditions recommended by TRS-398 protocol. Percentage depth was used as parameter comparison. Since obtained results both codes found maximum difference up to 2 % when experimental data before 6cm 2.2% MV 5.5 kV. Ratios between PPD PDD values showed build-up region, due highsensitivityive from incident fluency conditions. ratios significant differences solid-state rather than gel dosimeters, its low energy, angular dependence dosimeter, corroborating literature.
