Convert Gigacuries to Megabecquerels
Convert Gigacuries (GCi) to Megabecquerels (MBq) instantly and accurately.
Conversion Formula
MBq = GCi × 37000000000000
About Gigacuries
The gigacurie (GCi) equals 3.7 × 10¹⁹ Bq. The total fission product inventory of a 1 GWe nuclear power reactor at equilibrium is ~0.5 GCi; global spent fuel inventories worldwide exceed 10 GCi; total reactor-produced tritium in the world's oceans is estimated at ~1 GCi. 1 GCi = 3.7 × 10¹⁹ 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.
