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 Disintegrations per minute per gram

The disintegration per minute per gram (dpm/g) equals exactly 1000/60 Bq/kg ≈ 16.67 Bq/kg. Widely used in liquid scintillation counting (LSC) of ³H and ¹⁴C-labelled compounds and in nuclear forensics for soil and sediment analysis; geochemists report natural radionuclide concentrations in volcanic rocks and marine sediments in dpm/g. 1 dpm/g = 1000/60 Bq/kg.
