Convert Disintegrations per minute per gram to Millicuries per kilogram
Convert Disintegrations per minute per gram (dpm/g) to Millicuries per kilogram (mCi/kg) instantly and accurately.
Conversion Formula
mCi/kg = dpm/g × 4.504504505e-7
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 Millicuries per kilogram
The millicurie per kilogram (mCi/kg) equals 3.7 × 10⁷ Bq/kg = 37 MBq/kg. Radiopharmaceutical preparations are sometimes characterised in mCi/kg when assessing organ uptake per body mass; ⁹⁹mTc-labelled compounds have specific activities in the mCi/µmol range that translate to high mCi/kg values. 1 mCi/kg = 3.7 × 10⁷ Bq/kg.
