Radiometric Dating
A Christian Perspective
Dr. Roger C. Wiens
http://www.asa3.org/ASA/RESOURCES/WIENS.ht... Dr. Wiens has a PhD in Physics, with a minor in Geology. His PhD thesis was on isotope ratios in meteorites, including surface exposure dating. He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition. He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.
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. Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers. Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent. Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
This paper describes in relatively simple terms how a number of the 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 a number of misconceptions prevalent among Christians today. This paper is available on the web via the American Scientific Affiliation and related sites to promote greater understanding and wisdom on this issue, particularly within the Christian community.
More about the author: Dr. Wiens received a bachelor's degree in Physics from Wheaton College and a PhD from the University of Minnesota, doing research on meteorites and moon rocks. He spent two years at Scripps Institution of Oceanography (La Jolla, CA) where he studied isotopes of helium, neon, argon, and nitrogen in terrestrial rocks. He worked seven years in the Geological and Planetary Sciences Division at Caltech, where he continued the study of meteorites and worked for NASA on the feasibility of a space mission to return solar wind samples to Earth for study. Dr. Wiens wrote the first edition of this paper while in Pasadena. In 1997 he joined the Space and Atmospheric Sciences group at Los Alamos National Laboratory, where he has been in charge of building and flying the payload for the solar-wind mission, as well as developing new instruments for other space missions. He has published over twenty scientific research papers and has also published articles in Christian magazines. Dr. Wiens became a Christian at a young age, and has been a member of Mennonite Brethren, General Conference Baptist, and Conservative Congregational, and Vineyard denominations. He does not see a conflict between science in its ideal form (the study of God's handiwork) and the Bible, or between miracles on the one hand, and an old Earth on the other.
