How is the activity of a radioactive sample measured? In terms of the number of nuclear disintegrations per second. The Curie (Ci) is the unit used commonly, the Becquerel is the SI unit. The number of nuclear disintegrations that occurs in 1 second for 1 gram of radium, which is 3.7 x 10^10 disintegrations.
