Some of the commercial solid phantoms were unable to provide a good simulation to water at
low and high energy ranges. A potential phantom from Malaysian mangrove wood family,
Rhizophoraspp was fabricated with addition of Soy Protein. An Electron Gamma Sho
(EGSnrc) code was used to evaluate the dose distribution on Rhizophoraspp Soy Protein
phantom at 6 MV photon beam energy.  The result of the Rhizophoraspp Soy Protein phantom was then compared with the water phantom and the solid water phantom. This study showed that the uncertainty between Rhizophoraspp Soy Protein phantom and the water phantom and the solid water phantom is less than 8 % at certain depth. These comparable results have demonstrated the potential of the Rhizophoraspp Soy Protein phantom as another option for solid phantom in dosimetry purposes.

Keywords: mangrove wood; solid water phantom; water equivalent phantom; EGSnrc; depth dose.
