Meltdown Threat Rises in Japan

Fears of a nuclear meltdown have risen again in Japan, as the Fukushima Daiichi plant showed dangerously low water levels, exposing its uranium fuels rods and increasing the threat of radiation reaching the nearby public. And it’s not just one plant: a Japanese official said that there are meltdown fears at three of the nation’s nuclear facilities. At least 190 people have been exposed to radiation near Fukushima, officials say, and 185,000 people from the area have been evacuated, complicating rescue efforts the earthquake and tsunami.
