µCi/m³ = Bq/m³ × 2.702702703e-5
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.
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.
