The purpose of this chapter is to explain the process of radioactive decay and its relationship to the concept of half-life. Remember that a radionuclide represents an element with a particular combination of protons and neutrons nucleons in the nucleus of the atom.

He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.
