For some reason, which I have not yet figured out, at least one person per week has been asking me about the Carbon-14 Radiometric Dating Technique.They want to know if it is accurate or if it works at all.
In theory, it could even be used to date the Shroud of Turin." Rowe explained that the new method is a form of radiocarbon dating, the archaeologist's standard tool to estimate the age of an object by measuring its content of naturally-occurring radioactive carbon.
This process of ingesting C-14 continues as long as the plant or animal remains alive.
The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere.
Following death, however, no new carbon is consumed.
Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.
Because it reacts identically to C-12 and C-13, C-14 becomes attached to complex organic molecules through photosynthesis in plants and becomes part of their molecular makeup.
