Convert Rutherfords to Millibecquerels
Convert Rutherfords (Rd) to Millibecquerels (mBq) instantly and accurately.
Conversion Formula
mBq = Rd × 1000000000
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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.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 Millibecquerels
The millibecquerel (mBq) equals 10⁻³ Bq. Radiological surface contamination surveys in nuclear facilities use mBq/cm² alert levels for alpha and beta emitters; uranium and plutonium bioassay in urine from occupationally exposed workers is reported in mBq/sample. 1 mBq = 10⁻³ Bq = 10⁻³ s⁻¹.
