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.
This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.
When creation scientists studied granite samples, they made interesting discoveries.
Actually, that ratio may have been quite different.
For example, a worldwide flood would uproot and bury preflood forests.
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.
With less carbon-12 to dilute the carbon-14 continually forming from nitrogen in the upper atmosphere, the ratio of carbon-14 to carbon-12 in the atmosphere would increase.
Therefore, a radiocarbon year would not correspond to an actual year.
As explained in recent measurements show that the ratio of carbon-14 to carbon-12 has been building up in the atmosphere.
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.
They concluded that the helium in the rock was 100,000 times more plentiful than it should have been if the rocks were really 1.5 billion years old.
