They all start with similar flaws, but Carbon-14 has more than the rest.

The Carbon-14 “dating” method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.

Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.

Radiocarbon dating works by comparing the three different isotopes of carbon.

The total mass of the isotope is indicated by the numerical superscript.

While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.

There are more than 80 such technologies that are claimed to work.

Prior to looking at the many flaws in the Carbon-14 Dating Technique, it should be noted that no radiometric technique is reliable.

Everything from the fibres in the Shroud of Turin to Otzi the Iceman has had their birthday determined the carbon-14 way. There's plenty of hydrogen, oxygen and nitrogen in living things too, but carbon's got something none of them do — a radioactive isotope that can take thousands of years to decay.Working with several collaboraters, Libby established the natural occurrence of radiocarbon by detecting its radioactivity in methane from the Baltimore sewer.In contrast, methane made from petroleum products had no measurable radioactivity.Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.This means that although they are very similar chemically, they have different masses.

Not only that, we top up our carbon-14 levels every time we eat.
