114Cd
114Cd, also known as cadmium-114, is a radioactive isotope of cadmium with a half-life of approximately 284 days. It is produced through the decay of indium-114 and is a member of the indium-114 decay chain. Cadmium-114 emits beta particles and has a maximum beta energy of 1.05 MeV. It is a soft beta emitter, meaning its beta particles have low penetrating power and are easily shielded. Cadmium-114 is used in various applications, including as a tracer in medical imaging and as a source of beta particles in radiation therapy. Its radioactive properties make it useful in scientific research and industrial processes. However, due to its radioactivity, cadmium-114 requires proper handling and disposal to minimize exposure and environmental impact.
