Fukushima Health Risks Scrutinized

By Declan Butler of Nature magazine Even as the damaged reactors at the Fukushima Daiichi nuclear power station continue to leak radiation, researchers have begun laying the groundwork for studies that will look for any long-term effects on public health. Academic scientists face major obstacles as they try to collate baseline data on radiation doses in the face of the enormous disruption caused by the earthquake and tsunami that hit the country last month.

Fate of Nuclear Plant in Japan Hangs in the Balance as Melting Continues

As night fell on Friday in Japan, workers and soldiers continued heroic efforts to douse the potential meltdown underway at the Fukushima Daiichi nuclear power plant. The covering darkness is not the only reason for confusion: vital systems monitors have lost power, making the status of critical elements--such as the integrity of the nuclear fuel rods in reactor No.

Is Safe Nuclear Power Possible?

If the recent events in Japan were a movie, we'd say that the plot was too outlandishly catastrophic to be true--first an earthquake, then a tsunami, then a nuclear accident. Watching footage of entire neighborhoods being shoveled inland by roiling water, and knowing that those buildings and vehicles contained people, was horrifying.But while the citizens of Japan continue to struggle with their own personal hell, many

Should Japan’s Nuclear Reactor Crisis Kill the Nuclear Renaissance?

The hydrogen explosions, melting fuel rods and radiation leaks at Japan's Fukushima Daiichi nuclear plant are having an immediate impact on perceptions of nuclear power worldwide, at a time when many countries are earnestly searching for alternatives to fossil fuels. Safety will be a major concern, particularly as emergency workers in Japan continue to battle to keep spent fuel rods stored on site at Fukushima Daiichi from melting down. [More]

Workers Battle Fukushima Nuclear Crisis at Personal Risk

Braving explosions and invisible hydrogen fires as well as bursts of radiation at least eight times higher than government hourly safety standards, a cohort of 50 or so workers has returned to the embattled Fukushima Daiichi nuclear power plant in Japan. The workers represent the last line of defense in cooling the overheating reactors and spent fuel pools, such as reactor No

Fast Facts about Radiation from the Fukushima Daiichi Nuclear Reactors

Since a magnitude 9.0 earthquake rocked Japan and set loose a massive tsunami March 11, the Tokyo Electric Power Company (TEPCO) has been scrambling to avert a nuclear disaster at its hardest hit plant. The Fukushima Daiichi nuclear power station, home to six nuclear reactors, has witnessed explosions at three reactors and a fire in a spent-fuel pool at a fourth. At two reactors, units No.
