Convert Nanocuries per kilogram to Megacuries per kilogram
Convert Nanocuries per kilogram (nCi/kg) to Megacuries per kilogram (MCi/kg) instantly and accurately.
Conversion Formula
MCi/kg = nCi/kg × 1.000000000e-15
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.
About Megacuries per kilogram
The megacurie per kilogram (MCi/kg) equals 3.7 × 10¹⁶ Bq/kg. Encountered for extremely high-specific-activity nuclides: carrier-free ²²³Ra (α-emitter, t½ = 11.43 d) reaches ~50 MCi/kg; polonium-210 freshly separated from bismuth targets in research reactors has a specific activity near 4.5 MCi/g = 4.5 × 10³ MCi/kg. 1 MCi/kg = 3.7 × 10¹⁶ Bq/kg.
