mCi/kg = pBq/kg × 2.702702703e-20
About Picobecquerels per kilogram
The picobecquerel per kilogram (pBq/kg) equals 10⁻¹² Bq/kg. Environmental monitoring of very pure water samples and ultra-low-background detector materials reports natural radioactivity (²²⁶Ra, ²²⁸Ra) at pBq/kg; material purity screening for low-background physics experiments (neutrinoless double-beta decay searches) uses pBq/kg sensitivity thresholds. 1 pBq/kg = 10⁻¹² 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.
