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 Femtobecquerels
The femtobecquerel (fBq) equals 10⁻¹⁵ Bq, used in accelerator mass spectrometry (AMS) to quantify cosmogenic radionuclides (¹⁰Be, ³⁶Cl) in ice cores and geological samples. Ultra-low-background counting in deep underground laboratories reaches the fBq/kg level for solar neutrino detector purity assessment. 1 fBq = 10⁻¹⁵ Bq = 10⁻³ pBq.
