Fig. 4. Simulation geometry for calculating the energy deposition in the air slabs. An X-ray beam with a diameter of 10 mm was incident on the center of the front face of the air box. Fourteen air slabs with a thickness of 5-mm were piled from the bottom to the top of the air box and the energy deposited portion in each slab was calculated.
