How many months would I have to lay on a granite counter-top to receive that much exposure?

The number is a rate. Exposure is rate multiplied by time.

Now you could compare exposure rates... which vary with the flight. A good ballpark figure looks like maybe 0.5 millirem per hour, which is 5 microsieverts/hour. So the exposure rate the monitor is reading is about 20 times what you'd typically experience on a commercial jet flight.
