Do you know what level of keV is the beginning of an Alarm level?
Hi Pinto, "Gamma in energy range 600-800keV" - this is the radiation energy range that is being "counted" by the EPA equipment.
So, the number of counts (or detections) per minute (CPM) within that energy range are what we are concerned with.
Another way to look at it is - 800keV is not a count rate but an energy level, and the number of counts (or detections) within the energy levels 600-800keV are being recorded and charted for every minute. (CPM)
...OR... when an atom decays (or disintergrates) it releases energy. The energy it releases will be different depending on what the atom was (cesium, cobalt, etc, etc) before it disintergrated .
Now think of these different disintergration energies as different colours.
Call 600-800keV blue then "count" how much blue you can see.... But dont "count" the red (100-300keV)...
I hope this helps.
Peace
