US Patent 8067758 - Nanostructured nuclear radiation shielding
This patent teaches how nanostructured materials can be used to produce improved shielding for nuclear power plants or in medical diagnostic devices. Claim 1 reads:
1. A nuclear radiation and nuclear particles guiding material comprising:
a) a plurality of layers containing nanostructures, the nanostructures having the role to confine, guide and gyrate the nuclear radiation;
b) a plurality of layers comprising piezo-electric, ferro electric or magneto-electric material that changes the direction of the guided nuclear radiation inside the guide as a function of an electric signal applied on said material;
c) a plurality of layers having materials sensitive to the nuclear resonance of the radiation, wherein a selective nuclear radiation resonant absorber is formed therein and
d) a plurality of layers, fabrics or inserts to increase the chemical or heat resistance, as well as the resistance to radiation with energy lower than that of x-ray radiation energy.
