DPM

Disintegrations per minute count decays per minute; 60 dpm is one becquerel and 2.22 dpm is one picocurie.

Symbol: dpm

Quantity: activity of a radioactive source

SI relation: 1 dpm = 0.01666666666667 Bq (exact)

Derivation: 1 dpm = 1/60 Bq.

Exact: yes, by definition

Typical uses

Wipe tests and contamination surveys
Liquid scintillation counting
