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 ...
There are three isotopes of uranium: U-238, U-235, and U-234. Uranium decays naturally, and highly active isotopes are now in short supply. Apparently, whatever process created the uranium on ...
Low-enriched uranium is composed of around 5% uranium-235, the fissile isotope that splits to power nuclear reactors. In the long term, the government will need more highly enriched uranium, also ...
However, unlike the scarce and radioactive uranium-235 isotope, uranium-238 is stable ... As scientists initiate the process of artificial nuclear decay, uranium-238 atoms absorb neutrons in ...
Uranium is a radioactive element, meaning its atoms are unstable and decay over time ... A different isotope, uranium-235, is used in nuclear reactors and weapons, as U-238 cannot sustain a ...
