Actually, that ratio may have been quite different.
Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
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).
Radiocarbon ages do not increase steadily with depth, as one might expect. In other words, the concentration of carbon-14 is unexpectedly low in the lower organic layers.
As one moves to higher and higher layers, this concentration increases, but at a decreasing rate.
When granite rock hardens, it freezes radioactive elements in place.
The most common radioactive element in granite is Uranium-238.
Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.
