About Kilocuries

The kilocurie (kCi) equals 3.7 × 10¹³ Bq. ⁶⁰Co and ¹³⁷Cs blood irradiation and food sterilisation facilities use 20-200 kCi sources; research reactor fission product inventories are characterised in kCi; ⁹⁰Sr/⁹⁰Y radioisotope thermoelectric generators (RTGs) contain 10-150 kCi. 1 kCi = 3.7 × 10¹³ Bq.

About Rutherfords

The rutherford (Rd) equals exactly 10⁶ Bq = 1 MBq. Proposed by Ernest Rutherford and adopted at the 1946 Montreal Conference on Radioactivity as a convenient unit for large sources. Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
