How do you calculate CPM to DPM?
How do you calculate CPM to DPM? B. Determination of the Minimal Detectable Activity (MDA):Count the blank (background) for one minute.Calculate the MDA: SQRT (MDA (cpm) = 4.65 background (cpm))To obtain results in dpm, divide the MDA by the efficiency.Record all calculations and results in the lab notebook with the monthly lab wipes. Is DPM the same as CPM? The difference between counts per minute (CPM) and disintegrations per minute (DPM) lies in efficiency. Whereas DPM merely measures the number of atoms that decay in one minute given a select amount of radioactive material, CPM provides for the exact quantity...
