Corrosive, stinking Chinese drywall may be radioactive - Los Angeles Times

The final years of the U.S. housing boom and a disastrous series of Gulf Coast hurricanes created a golden opportunity for Chinese drywall manufacturers. With domestic suppliers unable to keep up with demand, imports of Chinese drywall to the U.S. jumped 17-fold in 2006 from the year before. That imported drywall is now at the center of complaints of foul odors seeping from walls. Hundreds of homeowners, most in Florida, have also reported corrosion to their air conditioners, mirrors, electrical outlets and even jewelry. State and federal authorities have traced the problems to Chinese-made drywall but haven't yet fully determined the causes. Some Chinese experts, however, suspect that the culprit is a radioactive phosphorus substance -- phosphogypsum -- that is banned for construction use in the U.S. but has been used by Chinese manufacturers for almost a decade.(china, building materials, defective products, health hazards)
