Plutonium
Plutonium is a radioactive, silvery-gray metal used primarily as fuel in nuclear reactors and as an explosive in atomic bombs. Discovered in 1940, it is produced by bombarding uranium with neutrons. Plutonium-239, a specific isotope, is essential for nuclear weapons due to its ability to sustain a chain reaction. While it has important applications in energy and defense, plutonium is hazardous due to its radioactivity and long half-life, which means it remains dangerous for thousands of years. Proper handling and disposal are critical to minimize environmental and health risks.

Plutonium-239 is a radioactive isotope of plutonium, primarily used as fuel in nuclear reactors and in the production of nuclear weapons. It is created from uranium-238 in nuclear reactors through neutron capture. Plutonium-239 has a half-life of about 24,100 years, which means it remains hazardous for a very long time. Its ability to sustain a nuclear chain reaction makes it valuable for energy production, but this also contributes to challenges regarding safety and nuclear proliferation. Proper handling and disposal are crucial due to its radioactive properties and potential environmental impact.
