It is also called radio carbon because it is radio active but not dangerous. The principle of superposition was recognized as early as by Steno.
Plants take in carbon dioxide, incorporating in their tissues both carbon unstable and normal carbon stable in the same proportion as they occur in the atmosphere.
The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the 14 C generated by cosmic rays to fully mix with them.

In addition, lava emerging later will tend to be hotter, coming from deeper in the earth and through channels that have already been warmed up.
No one expects that every one of those students will show up for a particular dance! This is called the biostratigraphic limit of the flow. His material comes directly from those folks at the Los Angeles Museum of Natural History who were involved in the excavation.
This would have prevented most of the carbon 14 from even forming. Animals that lived before the flood would have lived in a world with much less carbon 14 to begin with.
However, there may be other explanations for this apparent age. The biostrategraphic limits issue The issue about igneous bodies may need additional clarification.
Geologic carbon dating the Grand Canyon area the Cambrian lies beneath a huge column of strata; in California's Mojave Desert portions of the Cambrian are exposed at the surface.
Radiocarbon dating of vertical sequences of organic-rich layers at locations worldwide has consistently shown a surprising result.
The uncertainties inherent in radiometric dating are disturbing to geologists and evolutionists If the fossil only contains half as much carbon 14 as the atmosphere, it is assumed to have been dead for one half-life, or 5, years.
Then the partial pressure of argon 40 in the magma will never decrease below p; excess argon 40 will remain dissolved in the lava or magma as it cools.
Modern lava flows often come down the sides of volcanoes, and thus become separated from their source by large distances. For consistency with these early papers, and to avoid the risk of a double correction for the incorrect half-life, radiocarbon ages are still calculated using the incorrect half-life value.
In summary of these latter points, radiometric dating has passed a severe test whereas young-earth creationism flounders, in hopeless knots, on the basic facts of the geologic record. Furthermore, the question arises whether bentonite always gives correlated ages, and whether these ages always agree with the accepted ages for their geologic period.

This is from a paper by Austin available at ICR. When something of known age is dated: Rubidium parent atoms can be leached out of the rock by water or volatilized by heat. If we knew the amount of carbon in an organism when it died, we could attempt to date the time of death.
