Abstract:
A computational method for development of radiation shielding compositions, as described herein, can include selecting at least one polymer and at least one metal for each of a plurality of radiation shielding compositions, selecting a polymer:metal ratio for each composition, performing computational analysis to calculate an attenuation coefficient associated with a given radiation dose for each composition, identifying a best candidate composition for radiation shielding based on the calculated attenuation coefficients, and preparing a radiation shielding material including the at least one polymer, the at least one metal, and the polymer metal ratio associated with the best candidate composition.

Claim (Index 1):
A method for development of radiation shielding compositions, comprising the steps of:\n performing computational analysis on a computer to calculate a gamma radiation attenuation coefficient for at least nine distinct compositions, each of the compositions having a polymer matrix and functionalized particles of a single metal homogeneously dispersed in the polymer matrix in concentrations of 2%, 4%, 6%, 8%, and 10% w/w, respectively, in order to determine a concentration of the metal in the polymer matrix resulting in a maximum attenuation coefficient, thereby identifying the composition with optimal radiation shielding, wherein the polymer matrix comprises a polymer selected from the group consisting of polyacrylonitrile, polyethylene, and polyparaphenylene terephthalamide and the metal particles are selected from the group consisting of lead, gadolinium, and bismuth; preparing a radiation shielding material using the composition identified as having optimal radiation shielding by computational chemistry; and repeating the steps of performing computational analysis and preparing a radiation shielding material for metals having radiation attenuating properties and having different toxicities and different weight, wherein the repetitive steps are performed and calculated for a plurality of energy levels, the energy levels range from 3,000 MeV to 50,000 MeV.
