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.
In 2008 we could only calibrate radiocarbon dates until 26,000 years.
Now the curve extends (tentatively) to 50,000 years.
Please feel free to contact our lab staff to discuss the specific details of your samples.
Normal handling will not contaminate most sample types, however, samples should be protected from sources of extraneous carbon.The Bill & Melinda Gates Foundation is a Strategic Partner.more Radiocarbon dating has transformed our understanding of the past 50,000 years.Materials suitable for radiocarbon dating include charcoal, wood and other plant matter, soils and sediments, shells, bone, carbonates, dissolved inorganic carbonate (DIC), methane and hydrocarbons, and food products.A table of optimum and minimum sample sizes is provided below.The calibrated date is also presented, either in BC or AD or with the unit cal BP (calibrated before present - before 1950).
