For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million years. By measuring the ratio of lead to uranium in a rock sample, its age can be determined.
The activity concentration arising solely from the decay of the uranium isotopes (U-234, U-235 and U-238) found in natural uranium is 25.4 Bq per mg. In nature, uranium isotopes are typically found in ...

On This Day in 1951, Four Illuminated Lightbulbs in Idaho Were Evidence of the First Time a Nuclear Power Plant Generated ElectricityAs scientists initiate the process of artificial nuclear decay, uranium-238 atoms absorb neutrons in the reactor core, becoming relatively more fissionable plutonium-239 atoms. When a plutonium ...
