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 Millibecquerels per kilogram

The millibecquerel per kilogram (mBq/kg) equals 10⁻³ Bq/kg. Used for very low-level radioactivity in food and environmental samples; trace ¹³⁷Cs in ocean water and ²²⁶Ra in mineral waters are reported in mBq/kg; occupational bioassay detection limits for actinides in urine and feces are expressed in mBq/kg. 1 mBq/kg = 10⁻³ Bq/kg.
