=== Cosmogenic neutrons === {{uncited section|date=June 2022}} {{Main|Cosmogenic neutron}} Cosmogenic neutrons are produced from cosmic radiation in the Earth's atmosphere or surface, as well as in particle accelerators. They often possess higher energy levels compared to neutrons found in reactors. Many of these neutrons activate atomic nuclei before reaching the Earth's surface, while a smaller fraction interact with nuclei in the atmospheric air.<ref>{{Cite web |date=2022-10-26 |title=Cosmogenic Nucleide Principle - CEREGE |url=https://www.cerege.fr/en/equipment/laboratoire-national-des-nucleides-cosmogeniques/principle-of-cosmogenic-nucleides/ |access-date=2024-07-16 |website=www.cerege.fr |language=en-GB}}</ref> When these neutrons interact with nitrogen-14 atoms, they can transform them into [[carbon-14]] (14C), which is extensively utilized in [[radiocarbon dating]].<ref>{{Cite web |title=What is Carbon Dating? {{!}} University of Chicago News |url=https://news.uchicago.edu/explainer/what-is-carbon-14-dating#how |access-date=2024-09-19 |website=news.uchicago.edu |language=en}}</ref>
