This method requires less than 1g of bone, but few countries can afford more than one or two AMSs, which cost more than A0,000.Australia has two machines dedicated to radiocarbon analysis, and they are out of reach for much of the developing world.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.In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.This is particularly important for very old samples.

Because of this, radiocarbon chemists are continually developing new methods to more effectively clean materials.

Moving away from techniques, the most exciting thing about radiocarbon is what it reveals about our past and the world we live in.

Radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins.

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.
