In this study, wooden type materials made from walnut and mulberry trees with different surface area (5x5cm(2), 8x8 cm(2), 10x10cm(2), and 12x12cm(2)) have been investigated by using photon rays at 6 MV and 18 MV energies. X-rays were applied to walnut and mulberry wood materials by setting solid phantoms at grant angle of 0 degrees. Dose measurements on the surface area with different thicknesses (0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, 6 cm, 7 cm, 8 cm and 9 cm) have been surveyed.
