Conversion Formula
nCi = Rd × 27027.02703
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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
About Nanocuries
The nanocurie (nCi) equals 37 Bq. Sealed radioactive sources in laboratory instruments (electron-capture detectors in GC, ionisation chambers) are licensed in nCi; nCi is the working unit on US NRC licence forms and instrument calibration certificates for low-level sources. 1 nCi = 37 Bq = 3.7 × 10⁻⁸ Ci.
