Conversion Formula
GBq = pCi × 3.700000000e-11
About Picocuries
The picocurie (pCi) equals 3.7 × 10⁻² Bq = 37 mBq. The US EPA uses pCi/L as the standard unit for indoor radon (action level: 4 pCi/L) and drinking water radon; NRC licence exemption thresholds and natural uranium activity in groundwater are expressed in pCi/L. 1 pCi = 3.7 × 10⁻² 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.
