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.

About Kilocuries per kilogram

The kilocurie per kilogram (kCi/kg) equals 3.7 × 10¹³ Bq/kg = 1 Ci/g. The specific activity of carrier-free ⁶⁰Co is ~1124 Ci/g (= 1.124 kCi/kg or 4.16 × 10¹³ Bq/kg); many radionuclides produced without stable carrier have specific activities in the kCi/kg range. 1 kCi/kg = 3.7 × 10¹³ Bq/kg = 1 Ci/g.
