dc.description.abstractThe Malaysian mangrove hardwood, Rhizophora spp. has been extensively studied as a potential tissue equivalent material. However, the untreated Rhizophora spp. wood is unsuitable to be used as a phantom, due to its physical properties. Thus, the treated Rhizophora spp. particleboard was suggested as an alternative. The aim of this study was to explore the Rhizophora spp. particleboard with soy protein adhesive, as a potential phantom material, with its application validated using the Monte Carlo (MC) method at the radiotherapy energy range. The work was initiated by choosing the best mixture of the Rhizophora spp. with soy protein, based on its characteristics, i.e. density, electron density, dimensional stability, attenuation coefficient and effective atomic number. The addition of soy protein as an adhesive has resulted in a significant improvement in the particleboard’s dimensional stability. The Rhizophora spp. with particle size of 50–104 μm and 8 % soy protein has been chosen as the best mixture. The mixture was then used to fabricate the phantom with various thicknesses (0.4, 0.5, 0.6, 0.7, 0.8 and 0.9 cm) and densities (between 0.99 and 1.06 g/cm3). Meanwhile, the PRIMUS linear accelerator (LINAC) with photon (6 and 10 MV) and electron (6 and 15 MeV) beams were modelled using the EGSnrc/BEAMnrc code, while the dose distributions were calculated using the EGSnrc/DOSXYZnrc code. A commercial solid water phantom was used as a reference, to validate the performance of the Rhizophora spp. soy protein phantom. The percentage depth dose (PDD) result for the photon beam energies shows that the depth of maximum dose, dmax for the Rhizophora spp. soy protein phantom was identical with that of the standard water phantom.en_US
