How accurate is radiocarbon dating

More information
Though archaeologists can come up with good guesses about the date of artifacts through different processes, most methods of dating are trumped by a relatively new technique called radiocarbon dating. Developed in , it is considered the most useful way of determining the dates of artifacts for archaeologists. Since 14 C is radioactive, it decays at a relatively quick exponential rate Figure 1 , while non-radioactive carbon 12 C does not. While Libby noted that radiocarbon dating remains effective because the amount of 14 C produced in the atmosphere does not vary with time, this may not always be the case. Fossil fuel emissions have undoubtedly raised the amount of 12 C in the atmosphere, with there being an upward trend in in the metric tons of Carbon in the atmosphere since the industrial revolution Figure 2. When fossil fuels are released into the atmosphere, they release 12 C, and not 14 C.

Radiocarbon Dating’s New Calibration Curve - Archaeology Southwest

Radiocarbon dating can be quite accurate, and the techniques improve yearly. However, before accepting a radiocarbon date, one should understand how the technique works, its limitations, and its assumptions. One limitation is that the radiocarbon technique only dates material that was once part of an animal or plant. To understand the other capabilities and limitations of radiocarbon dating, we must first understand how it works and consider the flood. Most carbon atoms weigh 12 atomic mass units.

Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F.
