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.

About Microcuries per kilogram

The microcurie per kilogram (µCi/kg) equals 3.7 × 10⁴ Bq/kg = 37 kBq/kg. Used in US nuclear facility waste characterisation and NRC licence conditions for effluent releases; ¹³⁷Cs body burden in heavily exposed Chernobyl liquidators reached the µCi/kg level in the immediate aftermath. 1 µCi/kg = 3.7 × 10⁴ Bq/kg.
