Plutonium-244 is a rare isotope of the element plutonium, which is a heavy metal used primarily in nuclear reactors and weapons. It has a half-life of about 80 million years, making it one of the more stable isotopes of plutonium. Due to its long half-life, Plutonium-244 is found in trace amounts in nature, primarily as a result of the decay of heavier elements. This isotope is of interest in scientific research, particularly in the fields of nuclear physics and geology. Its unique properties allow scientists to study the processes of nuclear decay and the formation of heavy elements in the universe. However, Plutonium-244 is not commonly used in practical applications due to its scarcity and the complexities involved in handling radioactive materials.
