Convert Femtobecquerels per kilogram to Disintegrations per minute per gram
Convert Femtobecquerels per kilogram (fBq/kg) to Disintegrations per minute per gram (dpm/g) instantly and accurately.
Conversion Formula
dpm/g = fBq/kg × 6.000000000e-17
About Femtobecquerels per kilogram
The femtobecquerel per kilogram (fBq/kg) equals 10⁻¹⁵ Bq/kg. Used in accelerator mass spectrometry (AMS) to quantify cosmogenic radionuclide concentrations (¹⁰Be, ³⁶Cl) in ice cores, sediments, and geological minerals where activities per unit mass are at the femto-level. Ultra-clean radiochemistry purity assessments for solar neutrino detectors also reach fBq/kg sensitivities. 1 fBq/kg = 10⁻¹⁵ 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.
