Convert Disintegrations per minute per gram to Megacuries per kilogram
Convert Disintegrations per minute per gram (dpm/g) to Megacuries per kilogram (MCi/kg) instantly and accurately.
Conversion Formula
MCi/kg = dpm/g × 4.504504505e-16
About Disintegrations per minute per gram
The disintegration per minute per gram (dpm/g) equals exactly 1000/60 Bq/kg ≈ 16.67 Bq/kg. Widely used in liquid scintillation counting (LSC) of ³H and ¹⁴C-labelled compounds and in nuclear forensics for soil and sediment analysis; geochemists report natural radionuclide concentrations in volcanic rocks and marine sediments in dpm/g. 1 dpm/g = 1000/60 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.
