  2. Counts per minute - Wikipedia

    en.wikipedia.org/wiki/Counts_per_minute

    Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI unit of radioactivity, the becquerel (Bq), is equivalent to one disintegration per second. This unit should not be confused with cps, which is the number of counts received by an instrument from the source.

  3. Specific activity - Wikipedia

    en.wikipedia.org/wiki/Specific_activity

    [1] [2] It is usually given in units of becquerel per kilogram (Bq/kg), but another commonly used unit of specific activity is the curie per gram (Ci/g). In the context of radioactivity , activity or total activity (symbol A ) is a physical quantity defined as the number of radioactive transformations per second that occur in a particular ...

  7. Burn rate (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Burn_rate_(chemistry)

    In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature.
