Convert Curies per kilogram to Nanocuries per kilogram
Convert Curies per kilogram (Ci/kg) to Nanocuries per kilogram (nCi/kg) instantly and accurately.
Conversion Formula
nCi/kg = Ci/kg × 1000000000
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.
About Nanocuries per kilogram
The nanocurie per kilogram (nCi/kg) equals 37 Bq/kg. US EPA soil screening levels for ²²⁶Ra and ²²⁸Ra are given in pCi/g which equals nCi/kg; NRC derived concentration guides (DCGs) for radionuclides in soil for unrestricted-use release are expressed in nCi/kg in 10 CFR Part 20. 1 nCi/kg = 37 Bq/kg = 3.7 × 10⁻⁸ Ci/kg.
