I actually took my reading (high 400's) from the upper floor. The Radon guys say they expect about a 15% increase as you go down the house. So if you are 100 on the upper floor you'd be roughly 115 on the main and 132 in the basement. I also read that the lowest floor isn't necessarily the highest point of concentration.
