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 Becquerels
The becquerel (Bq) is the SI coherent unit of radioactivity, defined as exactly one nuclear disintegration per second. Named after Henri Becquerel (discoverer of radioactivity, 1896), it replaced the curie in SI. Household smoke detector ²⁴¹Am sources contain ~30 kBq; a banana contains ~15 Bq of ⁴⁰K. 1 Bq = 1 s⁻¹.
