Convert Curies per cubic metre (Ci/m³) to Disintegrations per minute per cubic metre (dpm/m³) instantly and accurately.
Conversion Formula
dpm/m³ = Ci/m³ × 2220000000000
About Curies per cubic metre
The curie per cubic metre (Ci/m³) equals 3.7 × 10¹⁰ Bq/m³ = 37 GBq/L. Encountered in concentrated radioactive liquid waste from nuclear reprocessing; reactor spent fuel pool water activity after fuel cladding failure; high-level waste (HLW) concentrates in storage tanks at Hanford, Sellafield, and similar sites. 1 Ci/m³ = 3.7 × 10¹⁰ Bq/m³.
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.
