Convert Picocuries per kilogram to Megacuries per kilogram
Convert Picocuries per kilogram (pCi/kg) to Megacuries per kilogram (MCi/kg) instantly and accurately.
Conversion Formula
MCi/kg = pCi/kg × 1.000000000e-18
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 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.
