Counts per Minute

Practical System

Counts per Minute (cpm)

Counts per minute (cpm) is a detector response, NOT true activity. Depends on detector efficiency, geometry, and radiation type. To convert cpm to dpm: dpm = cpm / efficiency. Efficiency varies from <1% (alpha) to >90% (some beta). Cannot directly convert to becquerels without knowing detector efficiency.
