Plutonium is a radioactive, silvery-gray metal that is used primarily as a fuel in nuclear reactors and as an essential material in the production of nuclear weapons. Its discovery and subsequent applications have made it a crucial element in the development of advanced scientific research, particularly in national laboratories focused on nuclear energy and defense.
congrats on reading the definition of plutonium. now let's actually learn it.
Plutonium was first produced in 1940 by scientists at the University of California, Berkeley, as part of research related to the Manhattan Project.
It has several isotopes, with plutonium-239 being the most significant for its use in nuclear weapons and as reactor fuel due to its ability to sustain a chain reaction.
The production of plutonium involves the irradiation of uranium-238 in nuclear reactors, where it absorbs neutrons and undergoes a series of decay processes to transform into plutonium.
Los Alamos National Laboratory has been central to plutonium research, including its handling, storage, and use in various applications ranging from energy generation to weaponry.
The handling of plutonium poses significant safety and environmental challenges due to its toxicity and long half-life, necessitating strict protocols for its management.
Review Questions
How did the discovery of plutonium influence scientific research at national laboratories?
