Neutron transport refers to the study of how neutrons move and interact within a medium, such as a nuclear reactor or a material used in radiation shielding. This process is crucial for understanding nuclear reactions, as neutrons can initiate fission in certain isotopes, like uranium-235. The transport of neutrons is influenced by factors such as scattering, absorption, and the geometry of the material. In neutron transport theory, mathematical models are used to predict the behavior of neutrons as they travel through different materials. These models help engineers and scientists design safer and more efficient nuclear systems, ensuring that the reactions occur as intended while minimizing radiation exposure to people and the environment.
