WebNov 15, 2016 · Low Enriched Uranium – contains a 235 U concentration between 0.711 percent and 20 percent. Most commercial reactor fuel uses low enriched uranium (LEU) enriched to between 3 percent and 5 percent 235 U. Uranium between 3 and 5 percent 235 U is sometimes referred to as “reactor-grade uranium.” WebIt’s naturally radioactive, but its isotope uranium-235 also happens to be fissile, as Nazi nuclear chemists learned in 1938, when they did the impossible and split a uranium nucleus in two. American physicists at U.C. Berkeley were soon to discover they could force uranium-238 to decay into plutonium-239 ; the substance has since been used ...
WebNatural uranium is mostly U-238 (~4.5 billion year half life; not useful on its own in most cases.) with a small amount of U-235 mixed in (0.4-2%, depending on quality; 235 is 'bomb uranium'; ~700million year half life). Both isotopes decay via Alpha (the most damaging type of radiation to your body).
