Radiometric Dating: Methods, Uses & the Significance of

Uranium – Lead Dating Method • Uranium-238 is a radioactive isotope that decays in a series of steps to lead-206 • Half-life of Uranium-238 is 4.5 billion years • Method of dating very old rocks by means of the amount of common lead they contain • Used to date rocks more than 10 million years old

As uranium-238 decays into lead-206, it will sometimes decay into a different isotope of its parent uranium isotope and sometimes it will decay into an isotope of a totally different element than its parent. This series of alpha and beta decays is known as the uranium-238 decay series..

C-14 and U-238 used for fossil dating? | Yahoo Answers

Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium-234 (234 U) and uranium-238 (238 U). It is one of several radiometric dating techniques exploiting the uranium radioactive decay series, in which 238 U undergoes 14 alpha and beta decay events on the way to the stable

In 1907, the American chemist Bertram Boltwood demonstrated that he could determine the age of a rock containing uranium-238 and thereby proved to the scientific community that radioactive dating was a reliable method. Uranium-238, whose half-life is 4.5 billion years, transmutes into lead-206, a stable end-product. Boltwood explained that by

How Carbon-14 Dating Works. Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years). The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy. However, radioisotope dating may not work so well in the

Radiometric Dating

The uranium-lead system in its simpler forms, using U-238, U-235, and thorium-232, has proved to be less reliable than many of the other dating systems. This is because both uranium and lead are less easily retained in many of the minerals in which they are found .

Uranium has a well-established radioactive decay series. U-238 and U-235 (which has 143 neutrons) are the most common isotopes of uranium. Uranium naturally contains all three isotopes (U-238, U-235 and U-234), and it rarely varies more than 0.01% from the average composition shown in the table below without our intervention.
