Two isotopes of uranium are used for radiometric dating uranium-238 decays to form lead-206 with a half-life of 447 billion years uranium-235 decays to form lead-207 with a half-life of 704 million years uranium-lead dating is usually performed on crystals of the mineral zircon (figure 1126. Dating methods that are claimed to give millions and billions of years—carbon dating can with radiometric dating dating method is the uranium-lead. One common radiometric dating method is the uranium-lead method this involves uranium isotopes with an atomic mass of 238 this is the most common form of uranium it decays by a 14-step process into lead-206, which is stable each step involves the elimination of either an alpha or a beta particle.

Radiometric dating and the age of the earth by ralph w matthews, phd [click here for a summary of this article] before 1955, ages for the earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular 45 billion years. An igneous rock sample is about 250,000 years old would you use uranium-lead radiometric dating to find its age - 5900064.

Radiometric dating geologist ralph harvey and historian mott greene explain the principles of radiometric dating and its application in determining the age of earth in this video segment from a science odyssey as the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.
