👉 Curies are a type of radioactive material that is used in many scientific and medical applications, including nuclear medicine. They are composed of a positively charged nucleus surrounded by negatively charged electrons and have a half-life of several years, which means they decay over time at a constant rate. Curies can be produced using various techniques such as neutron capture or magnetic field amplification, and are used in a variety of medical applications, including cancer treatment and imaging.
