All animals in the food chain, including carnivores, get their carbon indirectly from plant material, even if it is by eating animals which themselves eat plants.The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
This fact should always be remembered when using radiocarbon dates.
AMS, on the other hand, can in principle detect a much higher proportion (typically about 1% of the total) allowing sample sizes to be smaller by a factor of about a thousand.
The method is relatively new because it needs very complicated instruments first developed for Nuclear Physics research in the late 20th century.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for Carbon-14 measurements.
The lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.
