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 Petabecquerels

The petabecquerel (PBq) equals 10¹⁵ Bq. The Chernobyl accident (1986) released ~5200 PBq of noble gases and ~1760 PBq of ¹³¹I; Fukushima Daiichi (2011) released 400-900 PBq ¹³¹I-equivalent; global ⁸⁵Kr inventory from nuclear operations is ~1300 PBq. 1 PBq = 10¹⁵ Bq = 10³ TBq.
