kadmium113

Cadmium-113 is a radioactive isotope of cadmium. Its nucleus contains 48 protons and 65 neutrons. Cadmium-113 is a beta emitter, decaying into stable indium-113. The decay process releases beta particles and antineutrino. The half-life of cadmium-113 is approximately 9.3 x 10^15 years, making it an extremely long-lived isotope. Due to its very long half-life, it is considered a cosmogenic nuclide, meaning it is produced in small quantities by cosmic ray interactions in the Earth's atmosphere.

Cadmium-113 can also be produced artificially through various nuclear reactions, such as neutron capture by cadmium-112. Its radioactivity is relatively low compared to shorter-lived isotopes, but it is still a consideration in nuclear waste management and certain industrial applications. While not a primary concern in environmental contamination due to its scarcity and low activity, understanding its properties is important in specific scientific and industrial contexts. Its decay product, indium-113, is stable and does not pose a radiological hazard. The study of cadmium-113 contributes to our understanding of nuclear physics and the behavior of long-lived radionuclides.
