Convert Rutherfords to Microcuries
Convert Rutherfords (Rd) to Microcuries (µCi) instantly and accurately.
Conversion Formula
µCi = Rd × 27.02702703
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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.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 Microcuries
The microcurie (µCi) equals 3.7 × 10⁴ Bq = 37 kBq. Sealed sources for educational and bench-top laboratory use are licensed up to 1-10 µCi under US NRC 10 CFR 30.18; small-animal PET imaging doses of ¹⁸F in preclinical research are expressed in µCi. 1 µCi = 3.7 × 10⁴ Bq.
