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 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.
