Radiometric clocks are "set" when each rock forms. Applications of Nuclear Chemistry. So, we see there are a number of different methods for dating rocks and other non-living things, but what if our sample is organic in nature? The decay rate is referring to radioactive decaywhich is the process by which an unstable atomic nucleus loses energy by releasing radiation.

See the Teacher's Edition. With radiocarbon dating, the amount of the radioactive isotope carbon is measured.
These two uranium isotopes decay at different rates. The carbon it contained at the time of death decays over a long period of time. Conditions of Fossil Preservation: Prentice Hall Earth Science: Because plants use carbon dioxide for photosynthesis, this isotope ends up inside the plant, and because animals eat plants, they get some as well.

Carbon is a radioactive isotope of carbon it has two extra neutrons in uganda gay dating sites nucleus making it unstable. Absolute Time in Geology.
This provides a built-in cross-check to more accurately determine the age of the sample. Uranium is not the only isotope that can be used to date rocks; we do see additional methods of radiometric dating based on the decay of different isotopes. So, they do this by giving off radiation.
