Radiocarbon dating has transformed our understanding of the past 50, years.

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

Radiocarbon dating works by comparing the three different isotopes of carbon. 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. The total mass of the isotope is indicated by the numerical superscript. While the lighter isotopes 12 C and 13 C are stable, the heaviest isotope 14 C radiocarbon is radioactive.

This means its nucleus is so large that it is unstable. Over time 14 C decays to nitrogen 14 N. Most 14 C is produced in the upper atmosphere where neutrons, which are produced by cosmic rays , react with 14 N atoms. This CO 2 is used in photosynthesis by plants, and from here is passed through the food chain see figure 1, below. Every plant and animal in this chain including us!

Radiocarbon dating

When living things die, tissue is no longer being replaced and the radioactive decay of 14 C becomes apparent. Around 55, years later, so much 14 C has decayed that what remains can no longer be measured. In 5, years half of the 14 C in a sample will decay see figure 1, below. Therefore, if we know the 14 C: 12 C ratio at the time of death and the ratio today, we can calculate how much time has passed. Unfortunately, neither are straightforward to determine.

The amount of 14 C in the atmosphere, and therefore in plants and animals, has not always been constant. For instance, the amount varies according to how many cosmic rays reach Earth. Luckily, we can measure these fluctuations in samples that are dated by other methods. Tree rings can be counted and their radiocarbon content measured. A huge amount of work is currently underway to extend and improve the calibration curve. In we could only calibrate radiocarbon dates until 26, years.

Now the curve extends tentatively to 50, years. Radiocarbon dates are presented in two ways because of this complication. The uncalibrated date is given with the unit BP radiocarbon years before The calibrated date is also presented, either in BC or AD or with the unit calBP calibrated before present - before The second difficulty arises from the extremely low abundance of 14 C. Only 0. Many labs now use an Accelerator Mass Spectrometer AMS , a machine that can detect and measure the presence of different isotopes, to count the individual 14 C atoms in a sample.

Australia has two machines dedicated to radiocarbon analysis, and they are out of reach for much of the developing world.
