Radioactive dating uranium lead

Though uranium is highly associated with radioactivity, its rate of decay is so low that this element is actually not one of the more radioactive ones out there.

However, in reality, there is more lead than uranium.All other elements, which also decay to form lead 206, are ignored.Decay sequence from uranium 238 to lead 206: Using the model of a young Earth, the origin of the radiogenic lead present today could be traced back to several short-lived isotopes.In comparison, the most radioactive element is polonium. Still, uranium has explosive potential, thanks to its ability to sustain a nuclear chain reaction.U-235 is "fissile," meaning that its nucleus can be split by thermal neutrons — neutrons with the same energy as their ambient surroundings.On August 6, 1945, a 10-foot-long (3 meters) bomb fell from the sky over the Japanese city of Hiroshima.

Less than a minute later, everything within a mile of the bomb's detonation was obliterated.

Various methods are used for radiometric determination of the age of rocks. An unstable or radioactive initial material decays to form a different stable element.

The subsequent list shows how many other unstable elements also decay to form the same stable element: Generally, only the decay of uranium 238 is taken into consideration when using the uranium 238/lead 206 method (1).

In the model with a 4.5 billion-year-old Earth, the radiogenic lead can be traced back exclusively to the decay of long-lived isotopes. The decay time of short-lived isotopes is shown on the following internet site:

The half-life of these elements varies between a few microseconds and 245,500 years.
