Pros and cons of radioactive dating
It uses accelerator mass spectrometry to determine the amounts of C14 and C12 in a small sample which is vaporised in the test.The ions produced are forced into a magnetic field where the different mass of the carbon isotopes causes a different deflection, allowing the quantity of each isotope to be measured.
Usually a proton is knocked out of the nitrogen atom's nucleus and is replaced with the neutron.
This atom is not stable, and will break down, releasing nuclear energy in the process.
Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.
