Conversion Formula
Rd = MCi × 37000000000
About Megacuries
The megacurie (MCi) equals 3.7 × 10¹⁶ Bq. Total radioactive inventory of a large nuclear power reactor core at shutdown is ~2000-10000 MCi; US atmospheric nuclear weapons tests released ~12000 MCi of ¹³¹I globally; high-level nuclear waste repositories are characterised in MCi. 1 MCi = 3.7 × 10¹⁶ 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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
