Is carbon 14 dating accuracy

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.

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.

These cosmic rays collide with atoms in the atmosphere and can cause them to come apart.

So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.

An “isotope” is any of several different forms of an element, each having different numbers of neutrons.

The variation is certainly partially the result of a change in the cosmic ray production rate of radiocarbon.

The cosmic-ray flux, and hence the production rate of C-14, is a function not only of the solar activity but also of the magnetic dipole moment of the Earth.4Though complex, this history of the earth’s magnetic field agrees with Barnes’ basic hypothesis, that the field has always freely decayed....

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.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

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.
