About Exabecquerels
The exabecquerel (EBq) equals 10¹⁸ Bq. The global inventory of ⁴⁰K in the Earth's oceans is ~17 EBq; atmospheric nuclear weapons testing (1945-1963) deposited ~2 EBq of ¹⁴C globally; total natural radioactivity in the human body worldwide sums to ~10 EBq. 1 EBq = 10¹⁸ Bq = 10³ PBq.
About Curies
The curie (Ci) equals exactly 3.7 × 10¹⁰ Bq = 37 GBq, originally defined as the activity of 1 g of ²²⁶Ra. Still widely used in the US: ⁶⁰Co teletherapy sources are 5000-15000 Ci; ¹³⁷Cs blood irradiators are 1000-40000 Ci; NRC source licences for industrial radiography cite Ci limits. 1 Ci = 3.7 × 10¹⁰ Bq.
