Curium-241 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. Curium-241 has a half-life of about 24.1 years, meaning it takes that long for half of a sample to decay into other elements. This isotope emits alpha particles and gamma radiation, making it useful in various applications, including nuclear batteries and scientific research. Due to its radioactivity, handling Curium-241 requires safety precautions to protect against radiation exposure.
