Convert Picocuries per cubic metre to Microbecquerels per cubic metre
Convert Picocuries per cubic metre (pCi/m³) to Microbecquerels per cubic metre (µBq/m³) instantly and accurately.
Conversion Formula
µBq/m³ = pCi/m³ × 37000
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 Microbecquerels per cubic metre
The microbecquerel per cubic metre (µBq/m³) equals 10⁻⁶ Bq/m³. Routine air sampling at nuclear plant site boundaries reports ¹³⁷Cs, ⁵⁸Co, and ⁶⁰Co at µBq/m³; ²²²Rn progeny (²¹⁴Pb, ²¹⁴Bi) in well-ventilated outdoor air are typically tens of µBq/m³. 1 µBq/m³ = 10⁻⁶ Bq/m³ = 10⁻³ mBq/m³.
