It cannot be used directly to date rocks; however, it can potentially be used to put time constraints on some inorganic material such as diamonds (diamonds could contain carbon-14). Cosmic rays from outer space, which contain high levels of energy, bombard the earth’s upper atmosphere.

The procedures used are not necessarily in question. The secular (evolutionary) worldview interprets the universe and world to be billions of years old. The use of carbon-14 dating is often misunderstood.

Carbon-14 is mostly used to date once-living things (organic material). Carbon-14 is constantly being added to the atmosphere.

The earth has a magnetic field around it which helps protect us from harmful radiation from outer space. The stronger the field is around the earth, the fewer the number of cosmic rays that are able to reach the atmosphere.

This would result in a smaller production of The cause for the long term variation of the C-14 level is not known.

Neutrons that come from these fragmented atoms collide with C to be useful in age estimates.

This is a critical assumption in the dating process.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Recall that atoms are the basic building blocks of matter.
