Web10 feb. 2024 · Basics of Uranium-Lead Uranium comes in two common isotopes with atomic weights of 235 and 238 (we'll call them 235U and 238U). Both are unstable and radioactive, shedding nuclear particles in a cascade that doesn't stop until they become lead (Pb). The two cascades are different—235U becomes 207Pb and 238U becomes 206Pb.
