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 Petabecquerels per kilogram
The petabecquerel per kilogram (PBq/kg) equals 10¹⁵ Bq/kg. Carrier-free short-lived nuclides reach PBq/kg: freshly produced ⁹⁹mTc eluate at high specific activity approaches 10⁴-10⁵ GBq/mg = PBq/kg; freshly separated ³H gas from lithium targets in accelerators achieves PBq/kg specific activity values. 1 PBq/kg = 10¹⁵ Bq/kg = 10³ TBq/kg.
