The wood in these rings once laid down remains unchanged during the life of the tree.

This is very useful as a record of the radiocarbon concentration in the past.

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.

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.

Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes.

AMS (accelerator mass spectrometry) is used to determine the age of milligram samples of historical objects.

Radiocarbon, or Carbon-14, dating is probably one of the most widely used and best known absolute dating methods. Radiocarbon dating relies on a simple natural phenomenon.

This allowed for the establishment of world-wide chronologies.

This equipment was used at the University of Arizona (U of A) radiocarbon dating laboratory to date four of the Voynich Manuscript’s (VM) parchment pages.

A more realistic value for the U of A’s mean value would be 516±36 BP years, or 1424±13 AD years, instead of 1421±8.5 AD years.
