Doomed Chernobyl reactor to be buried in giant steel coffin - By MARIA DANILOVA, AP
In the two months after the disaster, 31 people died of radioactivity, but the final toll is still debated. The U.N. health agency estimates that about 9,300 will eventually die from cancers caused by Chernobyl's radiation. Groups such as Greenpeace insist the toll could be 10 times higher.
The old shelter, called a "sarcophagus," was built in just six months. But intense radiation has weakened it, according to the U.S. Nuclear Regulatory Commission, and rain and snow are seeping through cracks.
Officials say a tornado or earthquake could bring down the shelter, releasing clouds of poisonous dust.
