They are then able to calibrate the carbon dating method to produce fairly accurate results.
Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques.
The rapidity of the dispersal of C14 into the atmosphere has been demonstrated by measurements of radioactive carbon produced from thermonuclear bomb testing.
14C also enters the Earth's oceans in an atmospheric exchange and as dissolved carbonate (the entire 14C inventory is termed the carbon exchange reservoir (Aitken, 1990)).
during the industrial revolution more carbon-12 was being produced offsetting the ratio a bit).
Carbon dating is somewhat accurate because we are able to determine what the ratio was in the unobservable past to a certain extent.
By taking a carboniferous specimen of known age (that is, a specimen which we are able to date with reasonable certainty through some archaeological means), scientists are able to determine what the ratio was during a specimen's lifetime.
Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".
The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Thus, one carbon 14 atom exists in nature for every 1,000,000,000,000 C12 atoms in living material.
