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.Therefore, a radiocarbon year would not correspond to an actual year.
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.
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.
Outside the range of recorded history, calibration of the 14 clock is not possible.
This means the above calculations are only evolution speculation and NOT backed up by real science.
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.
When granite rock hardens, it freezes radioactive elements in place.
