Radiocarbon dating artefacts

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

In radiocarbon dating terms this makes the atmosphere appear older, which is reflected in the tissues of plants taking in CO2 during photosynthesis, and their products such as cottons.When these energetic neutrons collide with a nitrogen-14 (seven protons, seven neutrons) atom it turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

“If we reduced fossil fuel emissions, it would be good news for radiocarbon dating,” said the study’s author, Dr Heather Graven from the Department of Physics and the Grantham Institute – Climate Change and Environment at Imperial College London.
