Convert Picocuries per cubic metre to Becquerels per cubic metre
Convert Picocuries per cubic metre (pCi/m³) to Becquerels per cubic metre (Bq/m³) instantly and accurately.
Conversion Formula
Bq/m³ = pCi/m³ × 0.037
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 Becquerels per cubic metre
The becquerel per cubic metre (Bq/m³) is the SI derived unit of activity concentration. The WHO indoor radon reference level is 100 Bq/m³; EU Directive 2013/59/Euratom sets 300 Bq/m³ for residential radon in dwellings; normal outdoor ²²²Rn averages 5-15 Bq/m³ globally. 1 Bq/m³ = 1 s⁻¹ m⁻³.
