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.

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.

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.

Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.

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.

There are two main applications for radiometric dating.

One is for potentially dating fossils (once-living things) using carbon-14 dating, and the other is for dating rocks and the age of the earth using uranium, potassium and other radioactive atoms.

The atomic number corresponds to the number of protons in an atom.
