About Rutherfords
The rutherford (Rd) equals exactly 10⁶ Bq = 1 MBq. Proposed by Ernest Rutherford and adopted at the 1946 Montreal Conference on Radioactivity as a convenient unit for large sources. Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
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.
