Radioactive Materials
Radioactive materials are substances that emit radiation due to the presence of unstable atomic nuclei. 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-energy particles. However, the use of radioactive materials in space also poses significant safety and environmental risks, as well as regulatory challenges. Therefore, the handling, transportation, and disposal of radioactive materials in space require strict protocols and regulations.
