Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).

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.

Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.

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.

If the atmosphere's ratio of carbon-14 to carbon-12 has doubled since the flood and we did not know it, radiocarbon ages of things living soon after the flood would appear to be one half-life (or 5,730 years) older than their true ages.

If that ratio quadrupled, organic remains would appear 11,460 (2 x 5,730) years older, etc.

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.

They concluded that their findings are consistent with an Earth that is about 6,000 years old.

Half of it will decay in about 5,730 years to form nitrogen.

Half of the remainder will decay in another 5,730 years, and so on.

Therefore, a radiocarbon year would not correspond to an actual year.
