You probably have seen or read news stories about fascinating ancient artifacts.
This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
All living things exchange the gas Carbon 14 (C14) with the atmosphere around them—animals and plants exchange Carbon 14 with the atmosphere, fish and corals exchange carbon with dissolved C14 in the water.
Throughout the life of an animal or plant, the amount of C14 is perfectly balanced with that of its surroundings. The C14 in a dead organism slowly decays at a known rate: its "half life".
The SUERC results showed a 95% probability that the bone samples dated from around AD1430-1460, and over in Oxford the results both came out at around AD1412-1449, again with a 95% confidence. Radiocarbon dating of marine organisms can be out by up to several hundred years, and this effect can occur to a lesser degree in terrestrial life where sea-food forms part of the diet.
The mass spectrometry of the Greyfriars bone samples reveals that the individual in question had a high-protein diet including a significant proportion of seafood.
Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.
