Therefore:: 1 Ci = 3.7 × 1010 Bq = 37 GBq = 37,000,000,000 atoms decaying per secondand: 1 Bq ≅ 2.703 × 10−11 Ci ≅ 27 pCiAnother commonly used measure of radioactivity is the microcurie:: 1 μCi = 3.7 × 104 disintegrations per second = 2.22 × 106 disintegrations per minuteCorrespondingly, and more commonly encountered with natural levels of radiation, a picocurie is:: 1 pCi = 0.037 disintegrations per second = 2.22 disintegrations per minuteThe power in milliwatts emitted by one curie of radiation can be calculated by taking the number of MeV for the radiation times approximately 5.93.
