I don't know. Why don't you ask your teacher what he or she means?Suef said:When the teacher is asking for the definition of "Neutron activation and moderation" does he mean it together or separate. I google the quoted word but it gives "Neutron activation analysis". Is this the same thing or do I look separately the word "Neutron activation" and then "Neutron moderation".
Neutron activation is a process in which a material is bombarded with neutrons, causing its atoms to become radioactive.
When a neutron collides with an atom, it can either be absorbed or scattered. If it is absorbed, the atom becomes unstable and emits radiation, making it radioactive. This process is known as neutron activation.
The purpose of neutron activation is to create radioactive materials for scientific research, medical applications, and industrial uses such as detecting small amounts of impurities in materials.
Neutron activation involves the bombardment of materials with neutrons, while nuclear fission involves the splitting of atoms. Neutron activation does not release as much energy as nuclear fission and does not produce nuclear waste.
Neutron moderation is the process of slowing down fast-moving neutrons to increase their chances of being absorbed by an atom and causing neutron activation. This is usually done by using materials such as water or graphite.
