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 Gigabecquerels per kilogram
The gigabecquerel per kilogram (GBq/kg) equals 10⁹ Bq/kg. Characterises specific activity of cyclotron-produced short-lived nuclides: ¹⁸F batches from a medical cyclotron have specific activities of 10⁴-10⁵ GBq/µmol; ⁹⁹mTc eluates from a Mo/Tc generator are in the GBq/kg concentration range for clinical use. 1 GBq/kg = 10⁹ Bq/kg.
