nucleálását

Nucleálását is a term that can refer to several related concepts primarily within chemistry and nuclear physics. In a general chemical context, it denotes the process of nuclear transformation or reaction. This can encompass a wide range of phenomena, from the radioactive decay of unstable isotopes to the fission of heavy atomic nuclei or the fusion of light nuclei.

More specifically, the term might be used to describe the induced fission of fissile materials, such as uranium-235 or plutonium-239. This process is initiated when a neutron strikes the nucleus of a fissile atom, causing it to become unstable and split into two or more smaller nuclei, releasing a significant amount of energy, neutrons, and gamma radiation. This controlled chain reaction is the basis for nuclear power generation.

In nuclear physics, nucleálását can also refer to nuclear fusion, where two light atomic nuclei combine to form a single heavier nucleus. This process, exemplified by the fusion of hydrogen isotopes in stars, releases even greater amounts of energy than fission. Research into controlled nuclear fusion for energy production is ongoing.

The term is also sometimes used in a broader sense to discuss the fundamental changes occurring within the nucleus of an atom, regardless of whether it is a natural process or induced by external forces. Understanding nucleálását is crucial for fields ranging from nuclear medicine and materials science to astrophysics and national security.
