Radioactive Material
Radioactive material is any material containing atoms that are unstable and can spontaneously emit ionizing radiation. In the context of space and astronautical engineering, radioactive materials are used in various applications such as power generation, propulsion, and scientific instruments. For example, radioisotope thermoelectric generators (RTGs) use the heat generated by the decay of radioactive isotopes to produce electricity for spacecraft. Radioactive materials are also used in nuclear propulsion systems, which generate thrust by expelling high-speed particles from a nuclear reaction. However, the use of radioactive materials in space also poses significant safety and environmental risks, as any accidental release of radioactive material can have severe consequences for both human health and the environment.
