Converting from Curie (Ci) to Becquerel (Bq) | Radioactivity

What is Curie (Ci)

Curie (Ci) is a unit used to measure the activity of a radioactive substance. It is named after Marie and Pierre Curie, renowned pioneers in the field of radioactivity. One Curie is equivalent to 37 billion Becquerels.

What is Becquerel (Bq)

Becquerel (Bq) is the International System unit of radioactivity. The unit is named after Antoine Henri Becquerel, the physicist who discovered radioactivity. One Becquerel is defined as one radioactive decay event per second.
