Convert Kilocuries to Rutherfords
Convert Kilocuries (kCi) to Rutherfords (Rd) instantly and accurately.
Conversion Formula
Rd = kCi × 37000000
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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
