Curie
One curie is approximately the activity of 1 gram of the radium isotope 226Ra, equal to 3.7E+10 becquerels.
History: Named after Pierre and Marie Curie. Originally defined in 1910.
Current use: Still commonly used in the United States and in some clinical settings alongside the becquerel.
Also written as Ci, curies.
Disintegrations per second
The number of atomic nuclei that decay in one second.
History: A descriptive name for the rate of radioactive decay.
Current use: Used in physics and chemistry to describe activity directly.
Also written as dps, disintegrations per second.
