Convert Becquerels per cubic metre to Disintegrations per minute per millilitre
Convert Becquerels per cubic metre (Bq/m³) to Disintegrations per minute per millilitre (dpm/mL) instantly and accurately.
Conversion Formula
dpm/mL = Bq/m³ × 6.000000000e-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 Disintegrations per minute per millilitre
The disintegration per minute per millilitre (dpm/mL) equals exactly 10⁶/60 Bq/m³ ≈ 16 667 Bq/m³. Standard output unit of liquid scintillation counters (LSC) in biochemistry for ³H and ¹⁴C radiotracer assays; radioactivity in cell culture media, pharmacokinetic samples, and environmental water is routinely expressed in dpm/mL. 1 dpm/mL = 10⁶/60 Bq/m³.
