08.04.2017 · Carbon Dating: Determining the Rate of Radiocarbon Decay. After radiocarbon forms, the nuclei of the carbon-14 atoms are unstable, so over time they progressively decay back to nuclei of stable nitrogen-14. 3 A neutron breaks down to a proton and an electron, and the electron is ejected. This process is called beta decay. ...read more

### How carbon dating works? - Science ABC

01.08.2018 · This is the working principle of carbon dating: despite the transactions, a living organism maintains the same ratio of C-14 to C-12 atoms as found in the environment. However, when an organism dies, it ceases to consume carbon. Now, because C-14 is radioactive, it begins to decay. The ratio of C-14 to C-12 atoms in the organism now decreases. ...read more

First, there is a long-term oscillation with a period of about 9,000 years, which causes radiocarbon dates to be older than true dates for the last 2,000 years and too young before that. The known fluctuations in the strength of the earth's magnetic field match up quite well with this oscillation: cosmic rays are deflected by magnetic fields, so when there is a weaker magnetic field, more 14 ...read more
