About Gigabecquerels per kilogram
The gigabecquerel per kilogram (GBq/kg) equals 10⁹ Bq/kg. Characterises specific activity of cyclotron-produced short-lived nuclides: ¹⁸F batches from a medical cyclotron have specific activities of 10⁴-10⁵ GBq/µmol; ⁹⁹mTc eluates from a Mo/Tc generator are in the GBq/kg concentration range for clinical use. 1 GBq/kg = 10⁹ Bq/kg.
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.
