Radiological dating methods
Similarly, when all the atoms of the radioactive element are gone, the rock will no longer keep time (unless it receives a new batch of radioactive atoms).The rate of loss of sand from from the top of an hourglass compared to exponential type of decay of radioactive elements.But because God has also called us to wisdom, this issue is worthy of study.Rocks are made up of many individual crystals, and each crystal is usually made up of at least several different chemical elements such as iron, magnesium, silicon, etc.Most of the elements in nature are stable and do not change.However, some elements are not completely stable in their natural state.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.
Once all of the sand has fallen out of the top, the hourglass will no longer keep time unless it is turned over again.

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.
