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 Gigabecquerels
The gigabecquerel (GBq) equals 10⁹ Bq. Therapeutic radiopharmaceuticals are dosed in GBq: ¹⁷⁷Lu-PSMA prostate cancer therapy uses 7.4 GBq per cycle; ¹³¹I thyroid cancer ablation uses 3.7-7.4 GBq; ²²³Ra-dichloride (Xofigo) bone metastasis therapy ~3-5 GBq per injection. 1 GBq = 10⁹ Bq.
