  • The detection of alpha, beta, and gamma radiation enables the radioactivity of a source, a material or an object to be measured.
  • The unit used to measure radioactivity is the becquerel (Bq), which, since 1975, has replaced the curie (1 curie = 37 thousand million becquerels).
  • The activity of a source is measured in becquerels. One becquerel corresponds to the disintegration of one nucleus per second.
