About Becquerels per kilogram
The becquerel per kilogram (Bq/kg) is the SI derived unit of specific activity. It is the primary unit in food safety regulations worldwide: the EU, Japan, and Codex Alimentarius set ¹³⁷Cs limits in Bq/kg for foodstuffs; soil ¹³⁷Cs contamination from Chernobyl and Fukushima fallout is mapped in Bq/kg. 1 Bq/kg = 1 s⁻¹ kg⁻¹ = 1 mBq/g.
About Microbecquerels per kilogram
The microbecquerel per kilogram (µBq/kg) equals 10⁻⁶ Bq/kg. Very low-level anthropogenic contamination in drinking water (tritium, ⁹⁰Sr) and dietary exposures from global nuclear weapons test fallout in the 1950s-1960s are characterised at µBq/kg in body burden assessments. 1 µBq/kg = 10⁻⁶ Bq/kg = 10⁻³ mBq/kg.
