The dating system is an indispensable tool for archaeology, geology, and other earth sciences.
Radiocarbon dating is a branch of nuclear chemistry and physics.
All rocks and minerals contain tiny amounts of these radioactive elements.
The Mean Value quoted in this report encompasses an absolute range of 6% (plus and minus 3% on either side of the Mean Bio-diesel Result) to account for variations in end-component radiocarbon signatures (a conservative approximation).
It is presumed that all materials are present-day or fossil in origin, and that the desired result is the amount of bio-diesel component “present” in the material and NOT the amount of bio-diesel material “used” in the manufacturing process.
All living beings, plant and animal, will have the same concentration of carbon 14.
However, when the plants or animals die, their carbon 14 is no longer replaced from the atmosphere.
