Convert Disintegrations per minute per cubic metre to Megabecquerels per cubic metre
Convert Disintegrations per minute per cubic metre (dpm/m³) to Megabecquerels per cubic metre (MBq/m³) instantly and accurately.
Conversion Formula
MBq/m³ = dpm/m³ × 1.666666667e-8
About Disintegrations per minute per cubic metre
The disintegration per minute per cubic metre (dpm/m³) equals exactly 1/60 Bq/m³ ≈ 16.7 mBq/m³. Used in legacy US nuclear industry and older radiochemistry literature for low-level airborne radioactivity; some historical derived air concentration (DAC) limit publications cite values in dpm/m³. 1 dpm/m³ = 1/60 Bq/m³ ≈ 16.7 mBq/m³.
About Megabecquerels per cubic metre
The megabecquerel per cubic metre (MBq/m³) equals 10⁶ Bq/m³ = 1 kBq/L. ⁴¹Ar activity in the air of research reactor buildings during full-power operation commonly reaches MBq/m³; ³H concentrations in PWR primary coolant water are characterised in MBq/m³ (= kBq/L). 1 MBq/m³ = 10⁶ Bq/m³.
