Thus, geologists refer to uranium-lead (two versions), potassium-argon, rubidium-strontium, or samarium-neodymium dates for rocks.
Note that the carbon-14 (or radiocarbon) method is not used to date rocks, because most rocks do not contain carbon.
Isotopes are used as sources of radiation in medicine, sterilization, nondestructive control, etc.

Geologists regularly use five parent isotopes as the basis for the radioactive methods to date rocks: uranium-238, uranium-235, potassium-40, rubidium-87, and samarium-147.
These parent radioisotopes change into daughter lead-206, lead-207, argon-40, strontium-87, and neodymium-143 isotopes, respectively.
This process of changing the isotope of one element (designated as the parent) into the isotope of another element (referred to as the daughter) is called radioactive decay.
Thus, the parent isotopes that decay are called radioisotopes.
Each chemical element, such as carbon and oxygen, consists of atoms unique to it.
Isotopes are used as tracers in many medical settings.
Radioactive isotopes are used to identify abnormal bodily processes.
Both are complete atoms in every sense of the word.
Rather, it is a transmutation process of changing one element into another.
Actually, it isn’t really a decay process in the normal sense of the word, like the decay of fruit.
