1.1 Activity of a radioactive source
A radioactive sample is characterized by its activity (A), which is the number of disintegrations per unit of time.
The unit of activity is the becquerel, symbol Bq: 1 Bq = 1 disintegration per second.
The old unit of measurement for radioactivity was the curie (Ci) :
The radioactivity of a source decreases exponentially according to a factor specific to each radioelement, the radioactive...
