Radiation dust is like a gray-yellow haze that never goes away, weighing low on the slanted roofs of the rusty iron town. Qin Yu squatted on the steps in front of Qin's Qingdao House, wiping the old-fashioned radiation meter handed down from his grandfather with a greasy cloth. The pointer always stuck in the yellow range. Her thumbs habitually rubbed the worn metal on the edge of the instrument, and her eyes scanned the deserted streets. Another scavenger disappeared from the west end of the town.
