There are a number of ways to enter into a career in studying radiocarbon dating.Typically, a Master's Degree in chemistry is required because of the extensive lab work.As a test, the team took samples of acacia wood from two Egyptian Pharaohs and dated them; the results came back to within what was then a reasonable range: 2800BC /- 250 years whereas the earlier independent dates (largely the dendrochronology records) were 2625 /- 75 years (3), (5).Archaeologists had used Relative Dating methods to calculate their reigns.Increasingly though, students are learning about the principles of radiocarbon dates in archaeology, palaeontology and climate science degrees and can combine cross-disciplinary studies.The method developed in the 1940's and was a ground-breaking piece of research that would change dating methods forever. Libby calculated the rate of radioactive decay of the C isotope (4) in carbon black powder.Further information on the respective products may be found in the technical documentation and the product sheets in the table below.James Thomson (Meridian Technologies) was also so kind as to provide us with a presentation on the preparation and use of quench curves and the Do's and Don'ts of LSC.

Radiocarbon dating may only be used on organic materials.

The correction curves of counting efficiency for partially saturated solutions and for saturated solutions with quenching were prepared, respectively.
