Figure 5: (a) Relative depth dose curves (Monte Carlo simulated and film measured) for 6 MeV electron beam with 2 mm lead shielding placed at the depth of 1.5 cm compared to the standard percentage depth dose without lead. The percentage difference between Monte Carlo simulated and film measured percentage depth dose is shown in inset. (b) Relative depth dose curves (Monte Carlo simulated and film measured) for 9 MeV electron beam with 2 mm lead shielding placed at the depth of 2.0 cm compared to the standard percentage depth dose without lead. The percentage difference between Monte Carlo simulated and film measured percentage depth dose is shown in inset
