Calculates the dating in the past from the ratio of Uranium 235 in natural uranium. Current ratio of U235 in natural uranium is the same anywhere in the solar system. Because the half-life is different with U238 and U235, the higher the percentage of U235 so retroactively.
Uranium (U) 238 Radioactive Isotope Decay Calculator. Online radioactive decay calculator that allows you to find out the radioactivity decay in Uranium (U) 238. Note: The calculation of radioactivity in minerals is based on certain assumptions.
The Half Life of Uranium-238 is 4,500,000,000 years. There is even a radioactive isotope of carbon, carbon-14. Normal carbon is carbon-12. C-14 has two extra neutrons and a half-life of 5730 years. Scientists use C-14 in a process called carbon dating. Carbon dating is when scientists try to measure the age of very old substances.
You may also back decay sources to find out the original activity (or for any date), knowing the current activity. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to perform the calculation. You may enter date or time or a combination of both. Calendar pickers are included for date entry.
The Uranium-Lead (U-Pb) Dating is a method that encompasses several techniques that are employed in determining the geological age of both terrestrial and extraterrestrial (for example, meteorites) rocks. The method was first suggested by Boltwood in 1907 when he postulated lead to be the decay product of uranium. The method has a dating range from 4.55 x 109 years ago to approximately 5 x 104.

In uranium-lead (U-Pb) dating of zircon, the zircon is found to exclude initial lead almost completely. Minerals too are predictable chemical compounds that can be shown to form at specific temperatures and remain closed up to certain temperatures if a rock has been reheated or altered. A rock, on the other hand, may contain minerals formed at more than one time under a variety of conditions.Learn More
Uranium-thorium-lead dating, also called Common-lead Dating, method of establishing the time of origin of a rock by means of the amount of common lead it contains; common lead is any lead from a rock or mineral that contains a large amount of lead and a small amount of the radioactive progenitors of lead—i.e., the uranium isotopes uranium-235 and uranium-238 and the thorium isotope thorium-232.Learn More
Uranium-lead dating is usually performed on the mineral zircon (ZrSiO 4), though it can be used on other minerals such as monazite, titanite, and baddeleyite. Zircon incorporates uranium and thorium atoms into its crystalline structure, but strongly rejects lead. Therefore we can assume that the entire lead content of the zircon is radiogenic.Learn More
Uranium-238, U 238 Lead-206, Pb 206 Rubidium-87, Rb 87 Strontium-87, Sr 87. Basis of the Technique. As the parent element decays, its amount decreases while the amount of the daughter element increases. This gives us a ratio of parent:daughter elements. The decay rate is geometric rather than linear. Unaffected by heat or pressure. Key Term. Half-Life: the amount of time for half the atoms.Learn More
Uranium-series (U-series) dating is another type of radiometric dating. You will remember from our consideration of C-14 dating that radiometric dating uses the known rate of decay of radioactive isotopes to date an object. Each radioactive isotope has a known, fixed rate of decay. As its name suggests, uranium-series dating uses the radioactive decay of uranium to calculate an age. When.Learn More

Uranium-lead dating is one of the most complicated of all dating techniques. This is in part because uranium and lead are not retained in rocks as easily as some others, and in part because the parent isotopes and daughter products are not even directly related. For the isotopes uranium-235 and uranium-238 to respectively become lead-207 and lead-206, they must first undergo a serious of.Learn More
