Radiometric dating, radioactive dating or radioisotope dating is a technique used to date In these cases, usually the half-life of interest in radiometric dating is the longest one in the chain, which is the rate-limiting factor in .. 36Cl has seen use in other areas of the geological sciences, including dating ice and sediments.
Rubidium-strontium dating This is based on the decay of rubidium isotopes to strontium isotopes, and can be used to date rocks or to relate organisms to the rocks on which they formed. It suffers from the problem that rubidium and strontium are very mobile and may easily enter rocks at a much later date to that of formation. One problem is that potassium is also highly mobile and may move into older rocks. Due to the long half-life of uranium it is not suitable for short time periods, such as most archaeological purposes, but it can date the oldest rocks on earth.

These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope.
