Mind you, that's a trip across a parking lot (and I envision a Disney-sized lot, not the one at the local 7/11

) vs. an instant in the machine. If one were to spend the same amount of time in the x-ray machine that it would take to cross that lot, you'd be getting some really interesting dosages...
