Radiocarbon dating tools
Chances are, right now, you have a Gregorian calendar stuck to your wall.This calendar, with the months January through December, is a business standard used in many places round the world to define the year: one which hearkens back to Christian and Roman Imperial precedents.However, a number of things can easily go wrong during this stage of the process and the labs that calculate radiocarbon dates are subject to constant scrutiny to ensure that they are up to par; but even so, samples sent to different labs often produce slightly various results. These are established by a variety of elements, including but not limited to: the quality of the sample, the quality of the lab, and the age of the sample.It is when a sample is measured that the real complications begin: as the process to assign a meaningful date to the scientific chronology is rather erudite. dates (raw dates that are calibrated to the same calendar system are written without capital letters as b.c./ a.d. Younger samples have a larger margin of error than older samples.The dates given for Rapa Nui attract particular debate as they have been used to establish the time of the migration to the island.With carbon dating the type of sample and the placement of it within the site are very important.The date assigned to a sample will initially be given as a raw b.p. Often this margin of error is negligible in establishing a general chronology. Archaeology: Theories, Methods, and Practices (3rd edition).

But when a very precise timeline is needed, it can be very frustrating to have a margin of thirty years thwarting your efforts.

Radiocarbon dating is a side benefit of a naturally occurring scientific process.For periods without a historic record, attempts have been made to categorize tool kits, pottery styles, and architectural forms into regional timelines.Some ill-fated attempts to define time even attempted to count backwards through the genealogies of the Bible, establishing a series of dates which remain a cause of confusion.But other timekeeping methods exist and are still used in the modern world, circumventing the easy processing of dates and history between cultures.Throughout history, time has been defined in a variety of ways: by everything from the current ruler, or empire, or not defined at all.
This date can then be calibrated with dendrochronology, sediment cores, and/or other dating methods to ensure maximum accuracy and account for discrepancies in the amount of carbon fourteen in the atmosphere over the past few centuries. Regardless of these issues, carbon dating is still one of the most effective tools in the archaeologist’s kit.
