Unformatted text preview: decay. The unit used to measure radioactivity is the curie (Ci) where one curie equals 3.7 x 10 10 radioactive disintegrations per second (dps). The SI unit which may be used in place of the curie is the becquerel (Bq). These units are related as follows: O 1 Ci = 3.7 x 10 10 dps = 3.7 x 10 10 Bq. O 1 Bq = 1 dps . Another useful quantity is the amount of radioactivity per unit mass. This quantity, called specific activity , is typically measured in units of curies per gram (Ci/g)....
