Typical background radiation levels for most of the USA are in the 5 to 18 uR/hr range. Readings can be higher for brief periods of time due to normal variations in radiation levels. They can also be consistently higher for areas at high elevations, or with larger natural deposits of uranium, thorium, radon, etc.
Myself personally right now am more worried about if there is some sort of collective explosion that triggers a tsunami to come across and hit here (vancouver...and the rest of the west coast of course)
