Plutonium-239 decay products

Plutonium-239 (Pu-239) is a radioactive isotope used in nuclear reactors and weapons. Over time, Pu-239 undergoes radioactive decay, transforming into other elements through a process called a decay chain. It first decays into uranium-235 (U-235) by releasing radiation, then further transforms into isotopes of neptunium, plutonium-235, and eventually into stable lead isotopes. These decay products can emit radiation, which is why handling Pu-239 requires careful safety measures. Understanding its decay chain helps in managing nuclear materials and preventing environmental contamination.
