Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.Carbon-14 is created from nitrogen-14 in the upper atmosphere of the earth.Radiation from the sun collides with atoms in the atmosphere.When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.

Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.

Nitrogen normally occurs in a seven proton, seven nuetron, nitrogen-14 state.

When it collides with an energetic neutron it becomes carbon-14, with six protons and eight neutrons and gives off a hydrogen atom with one proton and zero neutrons. Carbon-14 is an isotope of carbon, which exists only is small amounts in the environment (1 in one trillion carbon atoms is carbon-14).

The approximate age of ancient artifacts can be determined as long as the artifact is not older than 50,000 years. All organisms that live on the Earth are based on carbon.

This would be wood, plants, animals and of course humans.

Accelerated Mass Spectrometry (AMS) as explained by, was started by J. I was even told long afterwards by a distinguished physicist who had been present at my (1897) lecture at the Royal Institution that he thought I had been, ‘pulling their legs.” This by
