DU is less radioactive than natural uranium because it has less U-235 per unit of mass. All traces of decay products have been removed during the chemical purification of uranium prior to enrichment.

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 ...

Uranium ore that miners dig up is relatively harmless. But it contains tiny amounts of a rare radioactive isotope, Uranium ...

Uranium-235 (U-235) is the only fissile radioactive isotope which exists ... it decays and transforms into another element. These decay elements, such as thorium and protactinium, produce ...

uranium-235 (U-235), accounts for 0.7%. Both U-238 and U-235 are radioactive, which means they decay and emit radiation in the process. U-238 decays very slowly or is barely radioactive ...

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 ...

While it is not common in the solar system, today its radioactive decay provides ... largely of two isotopes: uranium-238 (U-238), accounting for 99.3 percent and U-235 about 0.7 percent.

The term "nuclear waste" conjures up images of rusty steel drums leaking their glowing green radioactive ... enriched uranium, which is high in the fissionable isotope uranium-235.

Moreover, different types of fuel would produce different radioactive isotopes, and these might be identifiable from different neutrino signals. Specifically, they worked out that, whereas uranium-235 ...

X-rays were detected with an AMPTEK: XR-100CR In Nature, transmutation through radioactive decay can take millions or billions of years. For example, the half-life of Uranium-235 is 703.8 million ...
