The unit of radioactivity, Curie (Ci), and the International System of Units (SI) unit, Becquerel (Bq), are used to measure the rate at which a radioactive substance decays. Here's a brief explanation of each unit:
1. Curie (Ci): The Curie is a non-SI unit of radioactivity, named after Marie Curie. One Curie is defined as the activity of a quantity of radioactive material in which there are 3.7 x 10^10 disintegrations per second. In other words, 1 Ci is equivalent to 3.7 x 10^10 Bq.
2. Becquerel (Bq): The Becquerel is the SI unit of radioactivity. One Becquerel is equal to one disintegration per second. It is the more
