About Picocuries per kilogram
The picocurie per kilogram (pCi/kg) equals 3.7 × 10⁻² Bq/kg. Standard US unit for soil and sediment radioactivity screening: EPA soil screening levels for ²²⁶Ra and ²³‸U are cited in pCi/g (= nCi/kg); fish tissue ¹³⁷Cs limits in some US regulations use pCi/kg. 1 pCi/kg = 3.7 × 10⁻² Bq/kg.
About Curies per kilogram
The curie per kilogram (Ci/kg) equals 3.7 × 10¹⁰ Bq/kg = 37 GBq/kg. High specific activity sealed sources: ¹¹¹In and ¹³³Xe produced in accelerators are characterised in Ci/kg; ⁴²K formed by neutron activation in high-potassium food samples in research irradiators reaches Ci/kg values. 1 Ci/kg = 3.7 × 10¹⁰ Bq/kg.
