About Nanobecquerels per kilogram

The nanobecquerel per kilogram (nBq/kg) equals 10⁻⁹ Bq/kg. Marine radioactivity surveys measure transuranics (²³⁹Pu, ²⁴°Am) in deep-sea sediments at nBq/kg; CTBTO monitoring stations track fallout ¹³⁷Cs in aerosol filter samples approaching the nBq/kg level. 1 nBq/kg = 10⁻⁹ Bq/kg = 10⁻³ µBq/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.
