Most processes that we are familiar with are like sand in an hourglass.In exponential decay the amount of material decreases by half during each half-life.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.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.The goal is to promote greater understanding on this issue, particularly for the Christian community.Most of the elements in nature are stable and do not change.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
Some of the atoms eventually change from one element to another by a process called radioactive decay.
If there are a lot of atoms of the original element, called the parent element, the atoms decay to another element, called the daughter element, at a predictable rate.
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.
