Carbon dating method wiki

The 14C formed is rapidly oxidised to 14CO2 and enters the earth's plant and animal lifeways through photosynthesis and the food chain.

The rapidity of the dispersal of C14 into the atmosphere has been demonstrated by measurements of radioactive carbon produced from thermonuclear bomb testing.

Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.

Libby later received the Nobel Prize in Chemistry in 1960: (From Taylor, 1987).

Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon assays for the scientific community.

These isotopes are present in the following amounts C12 - 98.89%, C13 - 1.11% and C14 - 0.00000000010%.

Thus, one carbon 14 atom exists in nature for every 1,000,000,000,000 C12 atoms in living material.
