Maxing out a handheld geiger counter is misleading because they've got a sesitivity knob. A friend brought one to a party recently and showed everyone that their soda cans would max out the counter (at full sensitivity). Believe it or not, some people then refused to drink more soda because they thought it was contaminated. Better not bring them into a brick building!
