Conversion Formula
pBq = MCi × 3.700000000e+28
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 Picobecquerels
The picobecquerel (pBq) equals 10⁻¹² Bq. Environmental monitoring of drinking water reports naturally occurring ²²⁶Ra and ²²⁸Ra at pBq/L; ultra-low background Geiger counters in underground laboratories detect pBq-level contamination on detector surfaces. 1 pBq = 10⁻¹² Bq = 10⁻³ nBq.
