Convert Disintegrations per minute per cubic metre to Picobecquerels per cubic metre
Convert Disintegrations per minute per cubic metre (dpm/m³) to Picobecquerels per cubic metre (pBq/m³) instantly and accurately.
Conversion Formula
pBq/m³ = dpm/m³ × 16666666670
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 Picobecquerels per cubic metre
The picobecquerel per cubic metre (pBq/m³) equals 10⁻¹² Bq/m³. CTBTO International Monitoring System noble gas stations detect ¹³³Xe and ¸⁵Kr at pBq/m³ to identify covert nuclear tests; trace ¹³⁷Cs in pristine ocean-top air over the Pacific and Southern Ocean is measured at pBq/m³. 1 pBq/m³ = 10⁻¹² Bq/m³ = 10⁻³ nBq/m³.
