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 Terabecquerels per kilogram
The terabecquerel per kilogram (TBq/kg) equals 10¹² Bq/kg. Applies to short-lived nuclides of high specific activity: freshly separated ¹³¹I from reactor fission exceeds 1 TBq/kg; ⁶⁰Co sealed brachytherapy sources and ¹⁹²Ir radiography sources exhibit specific activities of several TBq/g, i.e. thousands of TBq/kg. 1 TBq/kg = 10¹² Bq/kg.
