Radiometric Dating It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating.

What are radiometric techniques?

The technique of measurement of natural radiation in the earths surface is called “radiometric method” (also known as Gamma ray spectrometry). This is a process in which the unstable atom becomes stable in the process of its nucleus. Energy is released in the form of radiation, viz., alpha, beta, and gamma rays.
