Radiometric Dating: A Christian Perspective by Roger C. Wiens, Caltech Geological & Planetary Sciences Division
Summary: Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them. It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the earth was created a very long time ago. Many Christians are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent, and they are also unaware that Bible-believing Christians are among those actively involved in radiometric dating. This paper describes in relatively simple terms how some dating techniques work, how accurately the half-lives of the radioactive elements and the rock dates themselves are known, and how dates are checked with one another. In the process the paper refutes some misconceptions prevalent among Christians today. God has called us to be "wise as serpents" even in this scientific age.
