Learn something new every day More Info Radiometric dating is a method by which the age of materials such as rocks can be determined. The process relies on the fact that certain atoms decay or transform at a measurable rate over time, meaning that age can be established by working out the rate of decay from a sample. The invention of radiometric dating was a crucial step in the process that determined the age of the Earth, a question that troubled scientists for centuries before finally reaching a largely accepted result in the 20th century. The discovery of radiometric dating is largely attributed to Ernest Rutherford, a British scientist who became interested in the study of radioactivity in the late 19th century. Radioactivity had only recently been introduced to the scientific community, mostly through the work of Marie and Pierre Curie. Rutherford, along with several collaborators, discovered that certain radioactive isotopes, which are elements with an unequal number of protons and neutrons, decay from an unstable version to a stable one.
The object's approximate age can then be figured out using the known rate of decay of the isotope.
For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms. Radiocarbon dating is one such type of radiometric dating.

All rights reserved. In order for a sample to be measured accurately, the unstable parent and stable daughter isotopes cannot have entered or left the sample after the material is originally formed. Since contamination is such a common issue, it is standard practice to test many different samples of a material in order to arrive at an accurate range.
The first truly accurate measurement of the age of the Earth was done by a geochemist named Clair Patterson in the late s. The genius of Patterson was in realizing that the best possible estimates for the age of the Earth could be made by using radiometric dating on meteorites, since meteorites date back to the formation of the solar system, and thus came into being around the same time of the Earth's birth.
Measuring the half life of uranium in meteoric samples, Patterson came up with an estimate of 4. One of our editors will review your suggestion and make changes if warranted. Note that depending on the number of suggestions we receive, this can take anywhere from a few hours to a few days.
