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 Millicuries per kilogram
The millicurie per kilogram (mCi/kg) equals 3.7 × 10⁷ Bq/kg = 37 MBq/kg. Radiopharmaceutical preparations are sometimes characterised in mCi/kg when assessing organ uptake per body mass; ⁹⁹mTc-labelled compounds have specific activities in the mCi/µmol range that translate to high mCi/kg values. 1 mCi/kg = 3.7 × 10⁷ Bq/kg.
