When a living thing dies, its radiocarbon loss (decay) is no longer balanced by intake, so its radiocarbon steadily decreases with a half-life of 5,730 years.
If we knew the amount of carbon-14 in an organism when it died, we could attempt to date the time of death.
However, before accepting any radiocarbon date, one should know how the technique works, its limitations, and its assumptions.
One limitation is that the radiocarbon technique dates only material that was once part of an animal or plant, such as bones, flesh, or wood. To understand the other capabilities and limitations of radiocarbon dating, we must understand how it works and consider the flood. However, roughly one in a trillion carbon atoms weighs 14 atomic units. It is also called radio carbon because it is radio active (but not dangerous).
The key questions then are: Has the atmospheric ratio of carbon-14 to carbon-12 changed in the past, and if so, why and how much?
Most carbon-14 quickly combines with oxygen to form radioactive carbon dioxide, which then spreads throughout the atmosphere.However, for the last 3,500 years, the increase in the ratio has been extremely slight.Radiocarbon dating of vertical sequences of organic-rich layers at 714 locations worldwide has consistently shown a surprising result.Plants take in carbon dioxide, incorporating in their tissues both carbon-14 (unstable) and normal carbon-12 (stable) in the same proportion as they occur in the atmosphere .Carbon-14 then moves up the various food chains to enter animal tissueagain, in about the same ratio carbon-14 has with carbon-12 in the atmosphere.
