WebWe call the uranium-238 the parent atom and the lead-206 the daughter atom. Understanding how long it takes for one element to become another element through radioactive decay is essential to absolute dating. A half-life is the time it takes for half of the atoms in an isotope to decay. One half-life of carbon-14 takes 5730 years. WebJun 8, 2024 · The half-life of 238 U is 4.5 billion years, i.e., the time it takes for half of the parent isotope atoms to decay into the daughter isotope. This isotope of uranium, 238 U, …

WebUranium–lead dating, abbreviated U–Pb dating, is one of the oldest [1] and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.
