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 Nanocuries per kilogram

The nanocurie per kilogram (nCi/kg) equals 37 Bq/kg. US EPA soil screening levels for ²²⁶Ra and ²²⁸Ra are given in pCi/g which equals nCi/kg; NRC derived concentration guides (DCGs) for radionuclides in soil for unrestricted-use release are expressed in nCi/kg in 10 CFR Part 20. 1 nCi/kg = 37 Bq/kg = 3.7 × 10⁻⁸ Ci/kg.
