Conversion Formula
Rd = kBq × 0.001
About Kilobecquerels
The kilobecquerel (kBq) equals 10³ Bq. Food safety authorities report ¹³⁷Cs contamination in kBq/kg (Codex Alimentarius and EC 733/2008 limits); ¹²⁵I tracers in radioimmunoassay kits are typically 3.7-18.5 kBq per well. 1 kBq = 10³ Bq = 1000 Bq.
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 Superseded by the MBq in SI but still encountered in older nuclear physics and reactor engineering literature. 1 Rd = 10⁶ Bq.
