Convert Megacuries to Petabecquerels
Convert Megacuries (MCi) to Petabecquerels (PBq) instantly and accurately.
Conversion Formula
PBq = MCi × 37
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 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.
