Following Friday's massive 8.9-magnitude earthquake that caused tsunamis and rocked the island nation of Japan, Japanese government officials announced a nuclear emergency after the quake caused a reactor cooling system malfunction at Fukushima No. 1 Nuclear Power Plant.
Ron Chesser, director for the Center of Environmental Radiation Studies at Texas Tech University, was the first American scientist allowed inside the exclusion zone in 1992 following the Chernobyl disaster. He can discuss issues that Fukushima workers may be facing in light of the cooling system troubles.
