Convert Picocuries per cubic metre to Microcuries per cubic metre
Convert Picocuries per cubic metre (pCi/m³) to Microcuries per cubic metre (µCi/m³) instantly and accurately.
Conversion Formula
µCi/m³ = pCi/m³ × 1.000000000e-6
About Picocuries per cubic metre
The picocurie per cubic metre (pCi/m³) equals 3.7 × 10⁻² Bq/m³ = 37 mBq/m³. Used by the US EPA and NRC for outdoor air radioactivity; airborne ⁹⁰Sr and ¹³⁷Cs near nuclear facilities are reported in pCi/m³; NRC occupational derived air concentration (DAC) tables list values in pCi/m³. 1 pCi/m³ = 3.7 × 10⁻² Bq/m³.
About Microcuries per cubic metre
The microcurie per cubic metre (µCi/m³) equals 3.7 × 10⁴ Bq/m³ = 37 kBq/m³. Used in US occupational radiation protection; NRC 10 CFR Part 20 DAC values for moderately radiotoxic nuclides are in the µCi/m³ range; air activity inside nuclear plant buildings after small sealed source incidents is assessed in µCi/m³. 1 µCi/m³ = 3.7 × 10⁴ Bq/m³.
