Radiometric dating is a technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes, and the current abundances.It is our principal source of information about the age of the Earth and a significant source of information about rates of evolutionary change.This predictability allows the relative abundances of related nuclides to be used as a clock that measures the time from the incorporation of the original nuclide(s) into a material to the present.The processes that form specific materials are often conveniently selective as to what elements they incorporate during their formation.If you're new to Wikia, please use the above links to get started.
Brokering shadowy deals for criminals across the globe, Red was known by many as "The Concierge of Crime." Now, he's mysteriously surrendered to the FBI with an explosive offer: he will help catch a long-thought-dead terrorist, Ranko Zamani, under the condition that he speaks only to Elizabeth "Liz" Keen, an FBI proﬁler fresh out of Quantico.
Although decay can be accelerated by radioactive bombardment, such bombardment tends to leave evidence of its occurrence.
