The term “curie” is a unit of radioactivity that is defined as the amount of a radioactive substance that undergoes 3.7 × 10^10 disintegrations per second. It is named after the French physicist Pierre Curie and his wife, Marie Curie, who conducted pioneering research on radioactivity. The curie is often used to measure the activity of radioactive materials, with the symbol “Ci” representing it.
