becquerel (Bq)
becquerel is a unit of radioactivity. Activity measures nuclear transformations per time: 1 Bq = 1 transformation per second; it does not measure absorbed dose.
curie (Ci)
curie is a unit of radioactivity: 1 Ci = 3.7 × 10¹⁰ Bq. Activity measures nuclear transformations per time: 1 Bq = 1 transformation per second; it does not measure absorbed dose.
