Counts Per Minute
Ionising radiation intensity is sometimes expressed as being a rate of counts per unit time registered by a radiation monitoring instrument. This measurement must not be confused with disintegrations per unit time, which represents the rate of atomic disintegration events that are taking place in the source of the radiation. Both counts and disintegrations can be expressed as a total amount integrated over any time period, but cps and cpm are generally accepted practical count rate measurements. Note that radiation intensity is the count rate, but this does not take into account the energy levels of the radiation being measured.
