About Picobecquerels per kilogram
The picobecquerel per kilogram (pBq/kg) equals 10⁻¹² Bq/kg. Environmental monitoring of very pure water samples and ultra-low-background detector materials reports natural radioactivity (²²⁶Ra, ²²⁸Ra) at pBq/kg; material purity screening for low-background physics experiments (neutrinoless double-beta decay searches) uses pBq/kg sensitivity thresholds. 1 pBq/kg = 10⁻¹² Bq/kg.
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.
