Carbon dating marine life is challenging, since many fish lack a hard body part where carbon builds up and can be measured. It may even be pegged at 1, to 1, years ago through carbon dating of the artifacts. Physical and chemical pretreatments are done on these materials to remove possible contaminants before they are analyzed for their radiocarbon content.

The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples. The principal modern standard used by radiocarbon dating labs was the Oxalic Acid I obtained from the National Institute of Standards and Technology in Maryland.

This oxalic acid came from sugar beets in When the stocks of Oxalic Acid I were almost fully consumed, another standard was made from a crop of French beet molasses. Over the years, other secondary radiocarbon standards have been made. Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis. Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.

A radiocarbon measurement is termed a conventional radiocarbon age CRA. The CRA conventions include a usage of the Libby half-life, b usage of Oxalic Acid I or II or any appropriate secondary standard as the modern radiocarbon standard, c correction for sample isotopic fractionation to a normalized or base value of These values have been derived through statistical means. American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.

He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter.

Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. It was also Mr. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating. Discovery of Radiocarbon Dating accessed October 31, Sheridan Bowman, Radiocarbon Dating: Interpreting the Past , University of California Press. Accelerator Mass Spectrometry AMS dating involves accelerating ions to extraordinarily high kinetic energies followed by mass analysis.

The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited. Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination.
