WebUranium is a silvery-white metal in the actinide series of the periodic table. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Uranium has the highest atomic weight of the primordially occurring elements. WebHowever, we can use the fact that different isotopes have different half-lives (the time it takes for half of the initial amount to decay), and estimate an age based on commonly used isotopes. Assuming that we are dealing with carbon-14, which has a half-life of 5,700 years, we can use the value of λ = ln(2)/5700 to calculate an approximate age: railings interior steelWeb230Th/U dating can provide high-precision age constraints on Quaternary hydrothermal sulfides.
