KORIYAMA, Japan (AP) — The U.N. nuclear agency says Japan has declared a state of emergency at another earthquake-affected nuclear plant where higher-than-permitted levels of radioactivity were measured.
The International Atomic Energy Agency says Japan informed it that the source of the radioactivity at the Onagawa power plant is being investigated. It said all three reactors at the plant are under control.

Japan also said authorities at another plant have resorted to using sea water to cool a second reactor in an attempt to prevent a meltdown.
Japan said earlier attempts to cool the No. 3 reactor at the Fukushima Dai-ichi plant had failed. Sea water is also being used to cool the plant's No. 1 reactor.
Sea water is corrosive and is being used as a last resort.
Chief Cabinet Secretary Yukio Edano also said Sunday that a hydrogen explosion could occur at Unit 3 of the Fukushima Dai-ichi nuclear complex, the latest reactor to face a possible meltdown. That follows a blast the day before in the power plant's Unit 1, and operators attempted to prevent a meltdown there by injecting sea water into it.
"At the risk of raising further public concern, we cannot rule out the possibility of an explosion," Edano said. "If there is an explosion, however, there would be no significant impact on human health."
More than 170,000 people had been evacuated as a precaution, though Edano said the radioactivity released into the environment so far was so small it didn't pose any health threats.
"First I was worried about the quake," Kenji Koshiba, a construction worker who lives near the plant. "Now I'm worried about radiation." He spoke at an emergency center in Koriyama town near the power plant in Fukushima.
The French Embassy urged its citizens Sunday to leave the area around Tokyo – 170 miles (270 kilometers) from Fukushima Dai-ichi – in case the crisis deepened and a "radioactive plume" headed for the area around the capital. The statement acknowledged that the possibility was looking unlikely.
Edano said none of the Fukushima Dai-ichi reactors was near the point of complete meltdown, and he was confident of escaping the worst scenarios.
A complete meltdown – the collapse of a power plant's ability to keep temperatures under control – could release uranium and dangerous contaminants into the environment and pose major, widespread health risks.
Up to 160 people, including 60 elderly patients and medical staff who had been waiting for evacuation in the nearby town of Futabe, and 100 others evacuating by bus, might have been exposed to radiation, said Ryo Miyake, a spokesman from Japan's nuclear agency. The severity of their exposure, or if it had reached dangerous levels, was not clear. They were being taken to hospitals.
Edano said operators were trying to cool and decrease the pressure in the Unit 3 reactor, just as they had the day before at Unit 1.
"We're taking measures on Unit 3 based on a similar possibility" of a partial meltdown, Edano said.
Japan struggled with the nuclear crisis as it tried to determine the scale of the Friday disasters, when an 8.9-magnitude earthquake, the most powerful in the country's recorded history, was followed by a tsunami that savaged its northeastern coast with breathtaking speed and power.
More than 1,400 people were killed and hundreds more were missing, according to officials, but police in one of the worst-hit areas estimated the toll there alone could eventually top 10,000.
The scale of the multiple disasters appeared to be outpacing the efforts of Japanese authorities to bring the situation under control more than two days after the initial quake.
Rescue teams were struggling to search hundreds of miles (kilometers) of devastated coastline, and hundreds of thousands of hungry survivors huddled in darkened emergency centers cut off from rescuers and aid. At least 1.4 million households had gone without water since the quake, and food and gasoline were quickly running out across the region. Large areas of the countryside were surrounded by water and unreachable. Some 2 million households were without electricity.
Japanese Trade Minister Banri Kaieda warned that the region was likely to face further blackouts, and power would be rationed to ensure supplies to essential facilities.
The government doubled the number of troops pressed into rescue and recovery operations to about 100,000 from 51,000, as powerful aftershocks continued to rock the country. Hundreds have hit since the initial temblor.
Unit 3 at the Fukushima plant is one of three reactors there that had automatically shut down and lost cooling functions necessary to keep fuel rods working properly due to a power outage from the quake. The facility's Unit 1 is also in trouble, but Unit 2 has been less affected.
On Saturday, an explosion destroyed the walls of Unit 1 as operators desperately tried to prevent it from overheating and melting down.
Without power, and with its valves and pumps damaged by the tsunami, authorities resorted to drawing sea water mixed with boron in an attempt to cool the unit's overheated uranium fuel rods. Boron disrupts nuclear chain reactions.
The move likely renders the 40-year-old reactor unusable, said a foreign ministry official briefing reporters. Officials said the sea water will remain inside the unit, possibly for several months.
Robert Alvarez, senior scholar at the Institute for Policy Studies and former senior policy adviser to the U.S. secretary of energy, told reporters that the sea water was a desperate measure.
"It's a Hail Mary pass," he said.
He said that the success of using sea water and boron to cool the reactor will depend on the volume and rate of their distribution. He said the dousing would need to continue nonstop for days.
Another key, he said, was the restoration of electrical power, so that normal cooling systems can operate.
Edano said the cooling operation at Unit 1 was going smoothly after the sea water was pumped in.
Operators released slightly radioactive air from Unit 3 on Sunday, while injecting water into it hoping to reduce pressure and temperature to prevent a possible meltdown, Edano said.
He said radiation levels just outside the plant briefly rose above legal limits, but since had declined significantly. Also, fuel rods were exposed briefly, he said, indicating that coolant water didn't cover the rods for some time. That would have contributed further to raising the temperature in the reactor vessel.
At an evacuation center in Koriyama, about 40 miles (60 kilometers) from the troubled reactors and 125 miles (190 kilometers) north of Tokyo, medical experts had checked about 1,500 people for radiation exposure in an emergency testing center, an official said.
On Sunday, a few dozen people waited to be checked in a collection of blue tents set up in a parking lot outside a local gymnasium. Fire engines surrounded the scene, with their lights flashing.
Many of the gym's windows were shattered by the quake, and glass shards littered the ground.
A steady flow of people – the elderly, schoolchildren and families with babies – arrived at the center, where they were checked by officials wearing helmets, surgical masks and goggles.
Officials placed five reactors, including Units 1 and 3 at Dai-ichi, under states of emergency Friday after operators lost the ability to cool the reactors using usual procedures.
An additional reactor was added to the list early Sunday, for a total of six – three at the Dai-ichi complex and three at another nearby complex. Local evacuations have been ordered at each location. Japan has a total of 55 reactors spread across 17 complexes nationwide.
Officials began venting radioactive steam at Fukushima Dai-ichi's Unit 1 to relieve pressure inside the reactor vessel, which houses the overheated uranium fuel.
Concerns escalated dramatically Saturday when that unit's containment building exploded.
Officials were aware that the steam contained hydrogen and were risking an explosion by venting it, acknowledged Shinji Kinjo, spokesman for the government's Nuclear and Industrial Safety Agency, but chose to do so because they needed to keep circulating cool water on the fuel rods to prevent a meltdown.
Officials insisted there was no significant radioactive leak after the explosion.
If a full-scale meltdown were to occur, experts interviewed by The Associated Press said melted fuel would eat through the bottom of the reactor vessel, then through the floor of the containment building. At that point, the uranium and dangerous byproducts would start escaping into the environment.
Eventually, the walls of the reactor vessel – six inches (15 centimeters) of stainless steel – would melt into a lava-like pile, slump into any remaining water on the floor, and potentially cause an explosion that would enhance the spread of radioactive contaminants.
If the reactor core became exposed to the outside, officials would likely began pouring cement and sand over the entire facility, as was done at the 1986 Chernobyl nuclear accident in the Ukraine, Peter Bradford, a former commissioner of the U.S. Nuclear Regulatory Commission, told reporters.
Another expert, physicist Ken Bergeron, told reporters that as a result of such a meltdown the surrounding land would be off-limits for a long time and "a lot of first responders would die."
The risk of radiation contamination from Japan's damaged nuclear power stations has sparked food bans across the globe and more surprisingly, a buying frenzy from South Korean mothers who fear their favorite Japanese-made diapers may suddenly become unavailable.
Cho Myung-jin, who organizes online group-buying for Japanese diapers, saw her website collapse on Tuesday under the weight of traffic as panicked South Koreans chased brands they believe are better quality than locally-made products.

Supply chain disruptions in Japan have forced at least one global automaker to delay the launch of two new models and are forcing other industries to shutter plants and rethink their logistical infrastructure.
Toyota Motor Corp (7203.T) said on Wednesday it would delay the launch in Japan of two new additions to the Prius line-up, a wagon and a minivan, from the originally planned end-April due to production disruptions from this month's devastating earthquake.
The world's biggest automaker has suspended production at all of its 12 domestic assembly plants at least through March 26 and has estimated a production loss of 140,000 vehicles until then.
The towering waves that splintered thousands of Japanese homes and lives has forced the country to rethink one of its most sacred Buddhist practices: how it treats the dead.
Desperate municipalities are digging mass graves, unthinkable in a nation where the deceased are usually cremated and their ashes placed in stone family tombs near Buddhist temples. Local regulations often prohibit burial of bodies.
An earthquake with a preliminary magnitude of 6.0 jolted parts of northern Japan near a quake-stricken nuclear power plant Wednesday, national broadcaster NHK said.
AOL spoke with Natalia Manzurova, a "cleaner" after the disaster in Chernobyl who suffered many side effects from radiation. Her advice to the people of japan was to leave quickly. She said:
Every nuclear accident is different and the impact cannot be truly measured for years. The government does not always tell the truth. Many will never return to their homes. Their lives will be divided into two parts: before and after Fukushima. They'll worry about their health and their children's health. The government will probably say there was not that much radiation and that it didn't harm them. And the government will probably not compensate them for all that they've lost. What they lost can't be calculated.

The Japanese tsunami cracked a vault wide open, leaving a perfect chance for an opportunistic thief. The AP reports:
The earthquake and tsunami that pulverized coastal Japan crippled a bank's security mechanisms and left a vault wide open. That allowed someone to walk off with 40 million yen (0,000).
The March 11 tsunami washed over the Shinkin Bank, like much else in Kesennuma, and police said between the wave's power and the ensuing power outages, the vault came open.
HuffPost blogger Simon Saradzhyan writes that despite the nuclear crisis in Japan, Russia presses on with it's nuclear program:
While Russian authorities saw the recent calamities in Japan as a chance to initiate a rapprochement with the country, Moscow's overtures to Tokyo have received a cool reception. However, Japan's nuclear crisis nonetheless represents an opportunity for Russian policy-makers to take a fresh look at the country's nuclear energy policies in order to ensure that both existing and future plants are protected against natural or man-made calamities, even those that may still seem unthinkable.

While radiation continues to leak from the reactor, the source is known, says the International Atomic Energy Agency. Reports Reuters:
"We continue to see radiation coming from the site ... and the question is where exactly is that coming from?" James Lyons, a senior official of the International Atomic Energy Agency (IAEA), told a news conference.
Washington, D.C.'s Cheery Blossom Festival will seek to encourage aid to Japan this year. Reports the AP:
Organizers of the National Cherry Blossom Festival in Washington are urging people to donate to the American Red Cross for earthquake relief efforts in Japan ahead of the festival that honors U.S.-Japanese relations.
Festival spokeswoman Danielle Piacente says they are working on plans to recognize the tsunami tragedy during the festival, which runs March 26 to April 10.
Japan's crisis will have macroeconomic repercussions beyond the country, the World Trade Organization (WTO) warned Tuesday.
Very small amounts of radiation have reached Iceland. Reuters reports:
Miniscule amounts of radioactive particles believed to have come from Japan's crippled Fukushima nuclear power plant have been detected as far away as Iceland, diplomatic sources said on Tuesday.
They stressed the tiny traces of iodine -- measured by a network of international monitoring stations as they spread eastwards from Japan across the Pacific, North America and to the Atlantic -- were far too low to cause any harm to humans.
Japan's human crisis is being compounded by an economic one. Reports Reuters:
The tsunami that hit Japan this month took such a huge toll on people, equipment and fish that supplies of some seafood could be cut off for a year or more, industry workers said on Tuesday.
The magnitude 9.0 quake on March 11 and the 10-meter (30-foot) tsunami it triggered are known to have killed more than 9,000 people and more than 12,000 are still missing.
But the damage to the coastline north of Tokyo has compounded the human tragedy with devastating commercial woes.

Power lines have been reconnected to all six nuclear reactor units. The AP reports:
The operator of Japan's leaking nuclear plant says power lines have been hooked up to all six reactor units, though more work is needed before electricity can run through them.
The plant's operator, Tokyo Electric Power Company, announced the hookup Tuesday but cautioned that workers must check pumps, motors and other equipment before the electricity is turned on.
Reconnecting the Fukushima Dai-ichi nuclear complex to the electrical grid is a significant step in getting control of the overheated reactors and storage pools for spent fuels. But it is likely to be days if not longer before the cooling systems can be powered up, since damaged equipment needs to be replaced and any volatile gas must be vented to avoid an explosion.

Japanese authorities have taken a major step in managing a nuclear crisis by connecting all six earthquake-damaged reactors to power supply, but it's too soon to say the crisis has reached a turning point, experts said on Monday.
Power has been connected but not switched on to crank up most coolers and pumps, which may have been badly damaged in the quake and tsunami that on March 11 triggered the world's worst nuclear accident since Chernobyl. Only one pump has been activated.
Reuters is reporting that the Fukushima plant had a history of safety concerns that are now under review:
When the massive tsunami smacked into Fukushima Daiichi, the nuclear power plant was stacked high with more uranium than it was originally designed to hold and had repeatedly missed mandatory safety checks over the past decade.
The Fukushima plant that has spun into partial meltdown and spewed out plumes of radiation had become a growing depot for spent fuel in a way the American engineers who designed the reactors 50 years earlier had never envisioned, according to company documents and outside experts.
At the time of the March 11 earthquake, the reactor buildings at Fukushima held the equivalent of almost six years of the highly radioactive uranium fuel rods produced by the plant, according to a presentation by Tokyo Electric Power Co to a conference organized by the International Atomic Energy Agency.
Along with questions about whether Tokyo Electric officials waited too long to pump sea water into the plants and abandon hope of saving them, the utility and regulators are certain to face scrutiny on the fateful decision to store most of the plant's spent fuel rods inside the reactor buildings rather than invest in other potentially safer storage options.
The first confirmed death of an American in Japan has been announced. Teacher Taylor Anderson was killed in the earthquake, officials say. MSNBC reports:
An American family was in mourning Monday after learning that their daughter and sibling, a teacher and lifelong student of Japanese culture, had been found dead in Japan –- the first known American victim of the March 11 earthquake and tsunami.
Taylor Anderson, a 24-year-old from Richmond, Va., had lived in Japan since August 2008. She was last seen after the powerful earthquake struck Japan on March 11, riding her bike away from the school where she taught after helping to get her students home.

Food radiation contamination is more serious than was originally thought. Reuters reports:
The World Health Organization said on Monday that radiation in food after an earthquake damaged a Japanese nuclear plant was more serious than previously thought, eclipsing signs of progress in a battle to avert a catastrophic meltdown in its reactors.
Engineers managed to rig power cables to all six reactors at the Fukushima complex, 240 km (150 miles) north of Tokyo, and started a water pump at one of them to reverse the overheating that has triggered the world's worst nuclear crisis in 25 years.
Some radiation has been found in seawater in Japan. Reports Reuters:

Miraculous survivor Jin Abe, who was found with his grandmother nine days after the quake, speaks here:
New estimates of the damage put the price tag at 0 billion. Reuters reports:
The Japanese earthquake and tsunami caused a total economic loss of up to 0 billion, about 5 percent of Japan's output, according to an initial estimate from risk modeling agency RMS.
The AP is reporting that smoke rising from two reactors caused workers to flee:
Gray smoke rose from two reactor units Monday, temporarily stalling critical work to reconnect power lines and restore cooling systems to stabilize Japan's radiation-leaking nuclear complex.
Workers are racing to bring the nuclear plant under control, but the process is proceeding in fits and starts, stalled by incidents like the smoke and by the need to work methodically to make sure wiring, pumps and other machinery can be safely switched on.
The AP reports that Yukiya Amano, the United Nations' nuclear chief, says government reponses to nuclear crisis are flawed:
The United Nations' nuclear chief says Japan's nuclear crisis has exposed serious problems in how governments respond to disasters, and how they must improve their responses.
Yukiya Amano says information must be transmitted more quickly by governments and that international experts must exchange information more rapidly.
He also said Monday in remarks to a 35-nation emergency meeting of the International Atomic Energy Agency that the role of the agency itself may need to be reviewed.
