Surface and Buildup Region Dose Measurements with Markus Parallel-Plate Ionization Chamber, GafChromic EBT3 Film, and MOSFET Detector for High-Energy Photon Beams

<div>Percentage depth doses (PDDs) for normally incident 15 MV photon beams at open fields with different sizes at 100 cm fixed SSD. The doses at 0, 1, 2, 3, 4, and 5 mm effective depths for each dosimeter were calculated by interpolation, and the following field sizes were investigated: 5 × 5 cm<sup>2</sup> (a), 10 × 10 cm<sup>2</sup> (b), and 20 × 20 cm<sup>2</sup> (c).</div>
