Materials can radiocarbon dating used
The introduction of "old" or "artificial" carbon into the atmosphere (i.e., the "Suess Effect" and "Atom Bomb Effect", respectively) can influence the ages of dates making them appear older or younger than they actually are.This is a major concern for bone dates where pretreatment procedures must be employed to isolate protein or a specific amino acid such as hydroxyproline (known to occur almost exclusively in bone collagen) to ensure accurate age assessments of bone specimens.What types of certain materials which can we date materials.
Radiocarbon dating can be used on either organic or inorganic carbonate materials.
However, there are a number of other factors that can affect the amount of carbon present in a sample and how that information is interpreted by archaeologists.
Thus a great deal of care is taken in securing and processing samples and multiple samples are often required if we want to be confident about assigning a date to a site, feature, or artifact (read more about the radiocarbon dating technique at:
While the lighter isotopes 12C and 13C are stable, the heaviest isotope 14C radiocarbon is radioactive.
This means its nucleus is so large that it is unstable. Most 14C is produced in the upper atmosphere where neutrons, which are produced by cosmic raysreact with 14N atoms.
Alone, or in concert, these factors can lead to inaccuracies and misinterpretations by archaeologists without proper investigation of the potential problems associated with sampling and dating.
