Chemistry and Chemical Reactivity
To obtain the data for the pre-1990 part of the curve shown in this graph,
scientists carried out carbon-14 dating ofartifacts for which the age was
accurately known (often through written records). Similar results can be obtained
using carbon-14 ...

... carbon 12, has varied somewhat during the past several thousand years. This
was determined by comparing ages established by carbon-14 dating ofwood
samples with ages established by counting annual tree rings in the same
samples.

As with all experimental procedures, carbon-14 dating has limitations. Although
the procedure assumes that the amount of carbon-14 in the atmosphere
hundreds or thousands of years ago was the same as it is now, in fact the
percentage has ...

CK-12 Earth Science for Middle School
The best-known method of radiometric dating is carbon-14 dating . A living thing
takes in carbon-14 (along with stable carbon-12). As the carbon-14 decays, it is
replaced with more carbon-14. After the organism dies, it stops taking in carbon.
