  • The activity (radioactivity) of a source, material, or object is measured via detection of alpha, beta, and gamma emissions.
  • The SI unit used to measure radioactivity is the becquerel (Bq), which, since 1975, has replaced the curie (1 curie = 37 thousand million becquerels); the US still uses Curies.
  • One becquerel corresponds to the disintegration of one nucleus per second.
