"Ten years later, the radiation remains. It's there in the soil; in the animals; in the people. Few know that better than three American scientists -- toxicologist Cham Dallas and geneticist Ron Chesser, both from the University of Georgia, and Texas Tech geneticist Robert Baker -- who are researching the accident's genetic effects in the shadow of Chernobyl's burned-out Reactor 4. It is research with ramifications beyond the contaminated 30-kilometer zone around Chernobyl. "We live in a society where Chernobyl may not simply remain here," said Dallas. "We may have a Chernobyl in America some day. Either from a nuclear reactor accident, or more likely, from use of a terrorist's nuclear weapon." It is research with relevance for people worldwide. "We are going to need this information. What are the consequences of long-term exposure to radionucleides inside the body? We're going to need to know," Dallas explained."
