About Picobecquerels
The picobecquerel (pBq) equals 10⁻¹² Bq. Environmental monitoring of drinking water reports naturally occurring ²²⁶Ra and ²²⁸Ra at pBq/L; ultra-low background Geiger counters in underground laboratories detect pBq-level contamination on detector surfaces. 1 pBq = 10⁻¹² Bq = 10⁻³ nBq.
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.
