Radioisotopes as Sources of Ionizing Radiation
Ionising radiation is produced by the radioactive decay of unstable atomic nuclei called radioisotopes. It is everywhere around us, has different abilities to penetrate matter and various properties that we can exploit.
Interaction of Atomic Nuclei with Particles
Subatomic particles can interact with atomic nuclei when they come within range of strong nuclear forces. Neutrons, protons or other particles can bounce off, excite the atomic nucleus, enter the nucleus or cause fission.
Nuclear Fuel and the Nuclear Fuel Cycle
The nuclear fuel cycle begins with mining and processing the ore, enriching to the required concentration of fissile isotopes and producing fuel assemblies. Spent fuel is temporarily or permanently stored or reprocessed.
The Principles of Operating a Nuclear Power Plant
Nuclear power plant generates energy by fission of atomic nuclei in the reactor core. The reaction is controlled by a moderator and absorber. The heat is transferred to a steam turbine which converts it into electricity.
The First Reactor and the First Nuclear Power Plant
The first nuclear reactor was built by Enrico Fermi from graphite and uranium, and in 1942, he started the first controlled fission reaction. In 1951, the electricity from the first nuclear power plant lit four light bulbs.
