  • The SI unit for measuring the amount of radioactivity is the becquerel (symbol Bq).
  • One becquerel (1Bq) is equal to 1 disintegration per second.
  • An older unit of radioactivity is the curie. The curie was originally defined as equivalent to the number of disintegrations that one gram of radium-226 will undergo in one second. 
  • Currently, a curie is defined using becquerels as 1Ci = 3.7 x 1010 disintegrations per second.
