Intro to Chemistry

Definition

The Curie (Ci) is a unit of radioactivity that quantifies the number of nuclear disintegrations per second. One Curie is equivalent to 3.7 x 10^{10} disintegrations per second.

congrats on reading the definition of Curie. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The Curie is named after Marie and Pierre Curie, pioneers in the study of radioactivity.
  2. 1 Curie corresponds to the activity of one gram of radium-226.
  3. The SI unit for radioactivity is the Becquerel (Bq), where 1 Ci = 3.7 x 10^{10} Bq.
  4. Curie is commonly used in medical applications such as cancer treatment and diagnostic imaging.
  5. While not an SI unit, the Curie is still widely used in various fields involving radioactive materials.
