Americium isotopes are variants of the chemical element Americium, which is a synthetic element with the atomic number 95. The most common isotopes are Americium-241 and Americium-243. These isotopes are produced in nuclear reactors and have applications in various fields, including nuclear medicine and industrial gauging. Americium-241 is particularly notable for its use in smoke detectors and as a radiation source in certain types of scientific research. Isotopes of Americium are radioactive, meaning they decay over time, releasing radiation. This property is essential for their applications but also requires careful handling and disposal.
