Section: claims

1. A radiological barrier material comprising a matrix and a particulate having a cross sectional dimension of about 500 micrometers or less contained within the matrix, the particulate comprising a radiation absorber that absorbs either one or both of alpha and beta radiation, the particulate comprising a defined nanostructure, the defined nanostructure comprising an aluminosilicate nanotube, the radiation absorber comprising a metal oxide, the radiation absorber further comprising an energy absorbing chromophore on the surface of the particulate. 2. The radiological barrier material of claim 1, wherein the radiation absorber further comprises a semiconductor. 3. The radiological barrier material of claim 1, wherein the matrix comprises an organic matrix. 4. The radiological barrier material of claim 1, wherein the matrix comprises an inorganic matrix. 5. The radiological barrier material of claim 4, wherein the inorganic matrix comprises a glass or a ceramic. 6. The radiological barrier material of claim 1, wherein the radiological barrier material is in the form of a fiber or a sheet. 7. A container for radiation emitting material, the container comprising the radiological barrier material of claim 1. 8. The container of claim 7, wherein the container comprises a flexible bag. 9. The container of claim 8, wherein the container is a single-layer flexible bag. 10. Personal protective equipment comprising the radiological barrier material of claim 1. 11. The personal protective equipment of claim 10, wherein the personal protective equipment comprises a glove. 12. The personal protective equipment of claim 10, wherein the personal protective equipment comprises a face shield or a body suit. 13. The radiological barrier material of claim 1, wherein the metal oxide comprises TiO2, FeO2, AlO2, CeO2, WO4, Cr2O3, SiO2, MgO2, CaO2, BaO2, CoO, VO2, NiO2, CuO2, ZnO, YO2, Na2WO2, ZrO2 or a combination of one or more metal oxides. 14. The radiological barrier material of claim 1, wherein the particulate is formed of the metal oxide.
