ABSTRACT:
A radiation-protection device is provided that includes a substrate and a surface structure formed on the substrate. The surface structure has an arrangement and interacts with radiation and the substrate to at least (a) substantially transmit or attenuate radiation at a wavelength and an energy below a threshold energy, and (b) substantially reflect radiation at the wavelength and an energy above the threshold energy.
