Se hela listan på courses.lumenlearning.com Since U-238 has a half-life of 4.5 billion years, it takes that amount of time for half of the original U-238 to decay into Pb-206. In a sample of rock that does not contain appreciable amounts of Pb-208, the most abundant isotope of lead, we can assume that lead was not present when the rock was formed. Depleted uranium (238 U) (depleted of uranium-235) is used in balistic armor penetration and as armor plating.

Indeed, the 238 U nucleus can absorb one neutron to produce the radioactive isotope uranium-239. The half-life for the radioactive decay of U-238 is 4.5 billion years and is independent of initial concentration. How long will it take for 10% of the U-238 a… There are a substantial number of radioactive isotopes of uranium, including U-234, U-235 and U-238, all three of which occur in the natural environment.

The radioactive decay is a purely  Radioactivity of U-238. This is just an example of how to calculate the radioactivity of an isotope from its halflife. Uranium 238 has a halflife of 4.468×10 9 years (  with the use of radioactive isotopes in identified industries and medicine The behaviour of U-238 and U-235 differs when bombarded by neutrons: 238. 1. 239. Radioactivity: Some isotopes are unstable and will sooner or later break up and one based on uranium-238's decay to lead-206 with a half-life of about 4.5  Element Uranium (U), Group 20, Atomic Number 92, f-block, Mass 238.029.
