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 Microcuries per kilogram
The microcurie per kilogram (µCi/kg) equals 3.7 × 10⁴ Bq/kg = 37 kBq/kg. Used in US nuclear facility waste characterisation and NRC licence conditions for effluent releases; ¹³⁷Cs body burden in heavily exposed Chernobyl liquidators reached the µCi/kg level in the immediate aftermath. 1 µCi/kg = 3.7 × 10⁴ Bq/kg.
