| Abstract Scope |
Ionizing radiation, such as gamma radiation, poses a large threat to human health and flourishing, a fact known for well over a century. Even so, as humans we find ourselves in extreme environments consisting of high concentrations of radiation rather often, such as during space exploration or times of war. Traditional shielding materials for electromagnetic radiation, like lead, are incredibly heavy for applications with weight constraints. As such, there is a pressing need for radiation shields which are lighter and more functional. Just like visible light, high energy electromagnetic radiation consists of electromagnetic waves which experience some amount of refraction and Fresnel reflection at interfaces. Nanostructured composite materials offer a pathway to maximize the number of these internal interfaces, thereby increasing their shielding performance and lowering their weight. This work explores the use of Field Assisted Sintering Technology (FAST) for the scalable synthesis of such nanocomposite gamma radiation shields. |
