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 Nanobecquerels
The nanobecquerel (nBq) equals 10⁻⁹ Bq. Atmospheric surveillance for tritium and ¹⁴C near nuclear facilities reports discharge rates in nBq/m³; EU drinking water directives set indicator activity concentrations for some radionuclides at the nBq/L level. 1 nBq = 10⁻⁹ Bq = 10⁻³ µBq.
