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.

About Petabecquerels

The petabecquerel (PBq) equals 10¹⁵ Bq. The Chernobyl accident (1986) released ~5200 PBq of noble gases and ~1760 PBq of ¹³¹I; Fukushima Daiichi (2011) released 400-900 PBq ¹³¹I-equivalent; global ⁸⁵Kr inventory from nuclear operations is ~1300 PBq. 1 PBq = 10¹⁵ Bq = 10³ TBq.
