When should I be worried?
A range of normal background radiation at this location at this time over several days has been determined to be between 40 to 46 CPM. These measurements are similar to background measurements taken in this location over long periods of time prior to the partial meltdowns in Japan.
Should radiation measured by the Inspector begin to rise to double background, we will be concerned. If the measurements go to triple background and above for a sustained period of time in the next few days, we might deduce that this may be coming from the Japan nuclear disaster.
