Fractional Probability of Compton Scattering Interaction of SPC-SPI Particleboards, Water and Solid Water Phantoms: (a) SPC/NaOH/IA-PAE/R spp. and (b) SPI/NaOH/IA-PAE/R spp. for the Photon Energy Range 6-15 MeV.

We developed soy protein concentrate–soy protein isolate bonded Rhizophora spp. particleboard phantoms using sodium hydroxide and a bio-based curing agent (itaconic acid polyamidoamine-epichlorohydrin resin). The probability of photon interactions was obtained at selected energies using Monte Carlo simulation with EGSnrc PEGS4 and used to interpola...

... becomes a dominant process. In the high-energy region, a particular phase of absorption begins to dominate, i.e. pair production (Attix, 1986;Khan, 2010). It is worth noting that the particleboard samples show almost similar variations throughout based on the dominance of different photon interaction processes in the different energy regions. From Figs. 2(a-b), it is observed that the interaction probabilities inside the particleboard samples are close to that of water and solid water phantoms within the energy range 6 MeV to 15 MeV. This demonstrates that SPC-SPI-based materials can be used as tissue substitute phantoms with an impact almost similar to water, particularly with respect to ...

Impending challenges in radiation dose estimation in patients especially in radiotherapy and nuclear medicine are of great concern. There is an urgent need to employ a human-like medium for verification before any radiation-related treatment or procedure to safeguard the patient and to ensure accuracy and efficiency of the treatment given. Rhizophora spp. is among the extensively studied alternative phantom material besides the widely commercialized resin-based phantom. This paper serves to review the evolution of Rhizophora spp. as phantom material and recent development of Rhizophora spp. phantom in medical physics applications and radiation study.
