 Sometimes [[textbook:nrctextbook:chapter6#activity|activities]] are expressed as a dps unit, meaning disintegrations per second which are equal to activities presented as [[textbook:nrctextbook:chapter6#becquerel|Becquerels]]. In some instances, for example in [[textbook:nrctextbook:chapter12|liquid scintillation counting]], activity is also presented as //dpm// units (disintegrations per minute). One dpm is 1/60 dps or 16.7 mBq. Sometimes [[textbook:nrctextbook:chapter6#activity|activities]] are expressed as a dps unit, meaning disintegrations per second which are equal to activities presented as [[textbook:nrctextbook:chapter6#becquerel|Becquerels]].
