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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.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 Exabecquerels

The exabecquerel (EBq) equals 10¹⁸ Bq. The global inventory of ⁴⁰K in the Earth's oceans is ~17 EBq; atmospheric nuclear weapons testing (1945-1963) deposited ~2 EBq of ¹⁴C globally; total natural radioactivity in the human body worldwide sums to ~10 EBq. 1 EBq = 10¹⁸ Bq = 10³ PBq.
