Carbon dating formula half life

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.

As our knowledge continues to grow, what we know continues to be in agreement with Scripture.

Radiocarbon ages less than 3,500 years old are probably accurate.

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.

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.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.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.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.
