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 Kilocuries per kilogram
The kilocurie per kilogram (kCi/kg) equals 3.7 × 10¹³ Bq/kg = 1 Ci/g. The specific activity of carrier-free ⁶⁰Co is ~1124 Ci/g (= 1.124 kCi/kg or 4.16 × 10¹³ Bq/kg); many radionuclides produced without stable carrier have specific activities in the kCi/kg range. 1 kCi/kg = 3.7 × 10¹³ Bq/kg = 1 Ci/g.
