Convert Nanobecquerels per cubic metre to Picocuries per cubic metre
Convert Nanobecquerels per cubic metre (nBq/m³) to Picocuries per cubic metre (pCi/m³) instantly and accurately.
Conversion Formula
pCi/m³ = nBq/m³ × 2.702702703e-8
About Nanobecquerels per cubic metre
The nanobecquerel per cubic metre (nBq/m³) equals 10⁻⁹ Bq/m³. Background ¹³⁷Cs in Northern Hemisphere air averages 10-100 nBq/m³ from post-Chernobyl and Fukushima residual deposition; ⁹⁰Sr near nuclear power plants is routinely monitored at nBq/m³ levels in air samples. 1 nBq/m³ = 10⁻⁹ Bq/m³ = 10⁻³ µBq/m³.
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.
