300 counts per minute is nothing, almost indistinguishable from standing in a grocery store.

- sponaugle 1y agoNot only that, but CPM (Counts per min) is measurement device specific. Using a very sensitive pancake probe will generate much higher CPM than a geiger tube from the same source. You have to look at calibrated units (usV/hr for example). Of course uSv has it own problems given the exposure model.. but better than CPM!
- michaelmrose 1y agoCPM isn't a actual measure without the service in question being specified.
