Figure 6: (a) Relative depth dose calculated using Monte Carlo simulations with 2 mm lead shielding placed at depths 0.5, 1.0, 1.5, 2.0, and 2.5 cm for 6 MeV electron beam. Relative dose reduction is seen when a 2 mm aluminum layer is placed over the lead shield at the depth of 1.5 cm.(b) Relative depth dose calculated using Monte Carlo simulations with 2 mm lead shielding placed at depths 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 cm for 9 MeV electron beam. Relative dose reduction is seen when a 2 mm aluminum layer is placed over the lead shield at the depth of 2.0 cm
