Bk-248, or Berkelium-248, is a synthetic radioactive isotope of the element Berkelium. It has an atomic number of 97 and is part of the actinide series on the periodic table. Bk-248 is produced in laboratories through the bombardment of Californium-249 with neutrons. This isotope has a half-life of approximately 24.5 hours, which means it decays relatively quickly. Bk-248 is primarily used for research purposes in nuclear chemistry and physics, helping scientists understand the properties and behaviors of heavy elements.
