See also Counterexamples to an Old Earth. Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant see below for the flaws in that assumption and measuring the amount of radioactive decay that has occurred. Because radiometric dating fails to satisfy standards of testability and falsifiability , claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence. It is more accurate for shorter time periods e. Radiometric dating proceeds from the fact that certain substances radioactive isotopes decay, with near-clockwork accuracy, into other elements, and that the old elements and the new elements can be chemically distinguished and can be quantitatively measured. Even the individual isotopes of an element can be accurately measured, though they can't be chemically separated.

Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. Radiometric Dating The aging process in human beings is easy to see.

Radioactive Decay The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state.

Half-Life So, what exactly is this thing called a half-life? Uranium-Lead Dating There are different methods of radiometric dating that will vary due to the type of material that is being dated. Potassium-Argon and Rubidium-Strontium Dating 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.

Radiocarbon Dating 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? Try it risk-free No obligation, cancel anytime.
