Web26 okt. 2024 · 1. Introduction. Radiocarbon dating is used to accurately determine the age of samples of biological material, and is a fundamental tool of modern archaeology [1,2].Thermal neutrons produced by cosmic rays interact with 14 N atoms in the upper atmosphere to produce radioactive 14 C, or radiocarbon, which filters across the … WebBecause 14 C is radioactive, it decays over time–in other words, older artifacts have less 14 C than younger ones. 14 C decays by a process called beta decay. During this process, an atom of 14 C decays into an atom of 14 N, during which one of the neutrons in the carbon atom becomes a proton.
