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 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.
