Fukushima's nuclear cauldron: Retirees who want to go in
Fukushima's radiation has hit deadly levels for the second day, according to Tepco, making efforts to bring the nuclear plant under control difficult. Japan’s retired skilled laborers say they are ready to relieve younger workers.
-
Fukushima radiation levels rise, area closed
Fukushima radiation has been found at potentially lethal levels at two locations. The area around the leaks has been evacuated.

New Mexico wildfires approach Los Alamos nuclear lab
New Mexico wildfires are near the boundaries of the 23,000-acre Los Alamos National Laboratory, which holds some low-level radioactive material in an above-ground storage facility about three miles from the flames.

Beyond Japan's Fukushima exclusion zone, shuttered shops speak to radiation doubts
As Japan's Tokyo Electric and Power Company tries to recycle the highly contaminated water at the Fukushima Daiichi nuclear power plant, people just outside the exclusion zone won't let children play outside and worry about food contamination.

Chernobyl disaster: four ways it continues to have an impact
Twenty-five years ago April 26, nuclear reactor No. 4 at the Chernobyl power plant exploded, sending waves of radiation across Ukraine and into neighboring countries. The disaster, which remains the world’s worst nuclear accident, continues to have an effect today. Here are four ways:

Robots throw doubt on 'road map' to control Fukushima crisis
Robots found high radiation levels in reactor buildings 1 and 3 Monday, which could make it impossible for workers to enter the Fukushima plant to carry out crucial fixes.
-
Fukushima gets worst crisis rating. But how much radiation has been released?
Based on new estimates of the radiation that has been released, Fukushima now has the worst score on the IAEA's accident rating scale. But much about the reactors, and their future, is still unknown.

Japan expands Fukushima evacuation zone. Will residents ever return home?
Radiation 'hot spots' beyond the existing Fukushima evacuation zone spur Japanese officials to order more areas to be emptied. Residents are being given a month to leave.

How do we know Fukushima isn't a danger to US? Radnet says so.
The 200 Radnet stations that have been sniffing the air since the 1970s say Fukushima radiation in US is quite low.

Nuclear update: Leak stopped. Why is Japan injecting nitrogen into reactor?
Workers plugged a leak of highly radioactive water into the ocean from Japan's Fukushima Daiichi nuclear power plant Wednesday, even as they tried to prevent another hydrogen explosion in reactor No. 1 by injecting nitrogen gas.

Radioactive milk harmless, but will consumers buy it?
Radioactive milk, detected in two states, contains tiny amounts of radioactive iodine that probably originated in Japan but pose no health threat. So far, milk sales seem steady.

Radioactive milk found on West Coast, but levels are 'minuscule'
Radioactive milk linked to the Japan nuclear crisis has been detected in samples from California and Washington State. But the amounts are so tiny that they pose no health risk, officials say.

How dangerous is nuclear power? Three lessons from Japan.
The devastated Fukushima Daiichi nuclear power plant has become the latest poster child for long-standing issues surrounding nuclear energy – issues that need to be resolved to reduce the risk of a similar nuclear crisis in the United States. These range from the seemingly eternal conundrum over dealing with highly radioactive spent fuel, to fire hazards, plant design, and emergency plans, say nuclear engineers and nuclear-safety watchdogs.

Kan says Japan on 'maximum alert,' but plutonium fears may be overblown
Low levels of plutonium found in soil near the stricken Fukushima Daiichi nuclear power plant do not appear to indicate that the crisis is worse than previously thought.

Radioactive seawater in Japan raises new fears of reactor crack
Levels of radioactive iodine reached 1,250 times above normal in seawater off the coast of Japan's stricken Fukushima Daiichi nuclear plant, raising concerns about a containment crack.
-
Japan nuclear update: Possible reactor breach, evacuation zone expanding
Three workers waded Thursday through water with critically elevated radiation levels. They are now being monitored, and officials are encouraging residents outside the initial evacuation zone to relocate.
-
Japan radiation levels uncertain: Should evacuation zone be bigger?
Difficulties in measuring radiation are increasing confusion in Japan. The government must weigh incomplete and sometimes contradictory data before making decisions.
