About Megabecquerels

The megabecquerel (MBq) equals 10⁶ Bq and is the standard clinical nuclear medicine unit outside the US. ⁹⁹mTc bone scans use 740 MBq; ¹⁸F-FDG PET scans use 370 MBq; ¹³¹I diagnostic thyroid scans use 185-370 MBq. European and Australian protocols specify all doses in MBq. 1 MBq = 10⁶ 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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
