Convert Picocuries to Disintegrations per minute

Convert Picocuries (pCi) to Disintegrations per minute (dpm) instantly and accurately.

Conversion Formula

dpm = pCi × 2.22

About Picocuries

The picocurie (pCi) equals 3.7 × 10⁻² Bq = 37 mBq. The US EPA uses pCi/L as the standard unit for indoor radon (action level: 4 pCi/L) and drinking water radon; NRC licence exemption thresholds and natural uranium activity in groundwater are expressed in pCi/L. 1 pCi = 3.7 × 10⁻² Bq.

About Disintegrations per minute

The disintegration per minute (dpm) equals exactly 1/60 Bq ≈ 16.7 mBq. Standard output unit of liquid scintillation counters (LSC) in biochemical and biomedical research for ³H and ¹⁴C tracer assays; radioimmunoassay protocols report results in dpm/well. 1 dpm = 1/60 Bq = 60 dph.
