We can measure in the laboratory how many carbon-14 atoms are still in the skull.

Radiocarbon (carbon-14 or C) forms continually today in the earth’s upper atmosphere.

First, it assumes that the rate of transformation of nitrogen to carbon 14 in the atmosphere is constant through time.

It turns out that this has not been the case and scientists have found greater/lesser abundances of carbon 14 in times past yielding dates that are to young or too old respectively.

Second, it assumes that there is no other source of carbon 14 in living things which has not been investigated very thoroughly.

Another complication has been recent reports that indicate that supposedly ancient sediments are producing trace amounts carbon 14 where there should be none at all.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.

A piece of ancient charcoal contains only 42% as much of the radioactive carbon as a piece of modern charcoal.

Radioactive and non-radioactive carbon dioxide mix throughout the atmosphere, and dissolve in the oceans.

The most well-known of all the radiometric dating methods is radiocarbon dating.

What exactly is carbon 14 testing and what are its limitations? Carbon 14 dating essentially tests how long something has been dead.

In the atmosphere solar radiation transforms a predictable number of nitrogen atoms into radioactive carbon (carbon 14).And as far as we know, it has been forming in the earth’s upper atmosphere at least since the Fall, after the atmosphere was made back on Day Two of creation week (part of the expanse, or firmament, described in Genesis 1:6–8).Cosmic rays from outer space are continually bombarding the upper atmosphere of the earth, producing fast-moving neutrons (sub-atomic particles carrying no electric charge) (figure 1).1 These fast-moving neutrons collide with nitrogen-14 atoms, the most abundant element in the upper atmosphere, converting them into radiocarbon (carbon-14) atoms.Although many people think radiocarbon is used to date rocks, it is limited to dating things that contain carbon and were once alive (fossils).
