dps\text{dps}

disintegration per second

Radioactivityexact by definition

A disintegration per second is exactly one becquerel; the becquerel is defined as one decay per second and dps is the older name for the same thing. It appears on legacy counting instruments and in radiochemistry procedures written before SI adoption.
