Curie refers to a unit of measurement used in the field of radioactivity. It is defined as the amount of radioactive material that produces 3.7 × 10^10 disintegrations per second. The unit is named after Marie Curie, a pioneering scientist known for her research on radioactivity, which earned her two Nobel Prizes. Marie Curie and her husband, Pierre Curie, discovered the elements polonium and radium. Their groundbreaking work laid the foundation for modern nuclear physics and medicine. The Curie family has made significant contributions to science, influencing various fields, including chemistry and physics.
