Conversion Formula
dpm/g = TBq/kg × 60000000000
About Terabecquerels per kilogram
The terabecquerel per kilogram (TBq/kg) equals 10¹² Bq/kg. Applies to short-lived nuclides of high specific activity: freshly separated ¹³¹I from reactor fission exceeds 1 TBq/kg; ⁶⁰Co sealed brachytherapy sources and ¹⁹²Ir radiography sources exhibit specific activities of several TBq/g, i.e. thousands of TBq/kg. 1 TBq/kg = 10¹² 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.
