Dianne Van Rossum put the hand-held, box-like X-ray device against the dingy, brown hallway wall. The gamma rays penetrated into the paint, found lead and bounced back to the X-RF lead paint analyzer.The machine read: .8 milligrams per square centimeter. Ms. Van Rossum took two more readings. She pushed down on the handle of the box and waited for the beep.
