Conversion Formula
pCi/kg = fBq/kg × 2.702702703e-14
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 Picocuries per kilogram
The picocurie per kilogram (pCi/kg) equals 3.7 × 10⁻² Bq/kg. Standard US unit for soil and sediment radioactivity screening: EPA soil screening levels for ²²⁶Ra and ²³‸U are cited in pCi/g (= nCi/kg); fish tissue ¹³⁷Cs limits in some US regulations use pCi/kg. 1 pCi/kg = 3.7 × 10⁻² Bq/kg.
