Type

Description

The curie (symbol Ci) is a non-SI unit of radioactivity, named after Marie and Pierre Curie. It is defined as $1 C i = 3.7 \times 10^{10} d e c a y s p e r s e c o n d$ . Its continued use is discouraged. One Curie is roughly the activity of 1 gram of the radium isotope Ra, a substance studied by the Curies. The SI derived unit of radioactivity is the becquerel (Bq), which equates to one decay per second. Therefore: $1 C i = 3.7 \times 10^{10} B q = 37 G B q$ and $1 B q \equiv 2.703 \times 10^{- 11} C i$ .
