In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws. Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.All carbon atoms have a nucleus containing six protons.As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.Carbon-14 is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.Benché come detto un singolo isotopo instabile possa decadere in qualsiasi momento, un numero sufficientemente grande di isotopi decade seguendo una legge esponenziale ad un tasso di decadimento descritto da un parametro detto tempo di dimezzamento.Dopo un tempo pari al tempo di dimezzamento, metà degli isotopi radioattivi sono decaduti.

It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.

La datazione radiometrica (o radiodatazione) è uno dei metodi per determinare l'età di oggetti antichi.

Essa si basa sul raffronto tra le abbondanze osservate di un opportuno isotopo radioattivo e dei suoi prodotti di decadimento (noto il tempo di dimezzamento, ed è la principale fonte di informazioni sull'età della Terra e sulla velocità dell'evoluzione delle specie viventi).

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.
