Carbon 14 dating equipment
Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air.
A reaction occurs and a tiny number of these collisions convert nitrogen to carbon-14.
After 50,000 years, a fossil won’t have any radiocarbon left in it.
Carbon-14 will have all disappeared by radioactive decay.
Their bodies are said to be in “equilibrium” with carbon-14 in the air.
This carbon dioxide rapidly mixes throughout the atmosphere, where at ground level it is taken in by plants during photosynthesis.Recently living materials (the biobased component) have Carbon-14 in them while fossil materials (derived from petroleum) no longer have this weakly radioactive carbon isotope.Thus all the carbon-14 in the product comes from the biobased component.Since it is radioactive, it gradually fades away by radioactive decay until it is all gone.Radiocarbon dating uses carbon-14 to determine the last time something (or someone) was alive.
