Curium-247 is a radioactive isotope of the element Curium, which is part of the actinide series in the periodic table. It has an atomic number of 96 and is produced through the decay of Plutonium-241 or by bombarding Plutonium with neutrons. Curium-247 has a half-life of about 15.6 million years, making it one of the more stable isotopes of curium. This isotope emits alpha particles and is primarily used in scientific research and nuclear applications. Due to its long half-life, Curium-247 can be found in some nuclear waste and is studied for its potential uses in advanced nuclear reactors and medical applications.
