Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. Radiometric dating, radioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities. Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed.

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive dating can also be applied to the dating of rocks as old as the Archaeologists, geologists, physicists can choose between array of radioisotopes. A technician of the U.

Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements. By "age" we mean the elapsed time from when the mineral specimen was formed. Radioactive elements "decay" that is, change into other elements by "half lives.
