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 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.
