Sea in the vicinity of Japan plant radioactive

Tuesday, April 05, 2011
26 March 2011 at 07:06 am, which says the Japanese Government most recently updated BBC Chris Hogg in Tokyo has tried to ensure that people about the work of SafetyLevels of radioactive iodine in the Sea close to the tsunami-stricken Fukushima are 1,250 times higher than the maximum safety of nuclear power plant, Officials say.

The readings were taken over about 300 m (984 ft) offshore. It is feared that the radiation in groundwater from one of the reactors be seeping could.

But the radiation can risk no longer after eight days, officials say.

There are areas of radioactive water in four of the reactors at the plant, and two workers are in the hospital.

The operator says, that the core of one of the six reactors victim.

She announced that fresh water instead of sea water to cool the damaged reactors, in the hope that this will be used more effectively.

Prime Minister Naoto Kan said the situation was "very unpredictable".

The official death toll of 11 March earthquake and tsunami has passed 10,000 and more than Dramburg missing people.

Hundreds of thousands of people made homeless; about 250,000 people live in shelters. Food, water and fuel are in short supply.

The Japanese Government has the reconstruction put costs at $309bn (? 191 billion).

Security measures

The levels of emissions in the Sea close to the facility found more than eight times were higher than in the same area last week, Japanese officials said.

A spokesman for Japan's nuclear agency said the radioactivity in the sea before the nuclear power plant was "relatively high", but the impact on the marine life would be minor.

"Generally" spokesman Hidehiko Nishiyama said a press conference, "radioactive material into the sea expands as a result of the tides, so must you much more for algae and sea live, to take."

He continued: "and because [iodine] has a half-life of eight days, from the time people eat the seafood be will have expected to be considerably reduced."

The contamination probably came from two airborne radiation from the reactors or Mr Nishiyama said tainted water released spilled into the sea.

Prime Minister Kan in a televised speech on Friday, said: "The situation is still very unpredictable." We are working to stop the situation from worsening. "We must be remain extremely vigilant."

He thanked also the workers to try fire-fighters and self-defense that cool reactors in the Prefecture Fukushima Daiichi plant forces for "Danger".

Japan's chief Cabinet Secretary Yukio Edano a rigorous investigation is in progress said establish the cause of a leak at the plant after testing water into the turbine showed halls of reactors 1 and 3 had 10,000 times higher than normal radiation levels.

Japan's nuclear agency reaffirms has confirmed, that it believes the reactor was damaged, but it goes no further than that, says the BBC's Mark Worthington in Tokyo.

The Agency has denied any suggestion that the reactor core may have cracked, Kyodo news reports.

The two affected workers who remain in the hospital, had allegedly was not wearing the correct protective boots and had ignored a radiation alarm in the work.

A review of security measures has been appointed.

The Government has asked the nuclear plant to voluntarily leave more people in 20-30 km (12-18 miles). So far, residents had come in the zone, stay indoors.

Food fears

Japan has banned nuclear grown deliveries of food in several prefectures around the damaged plants.

Police search for missing persons in KamaishiSearch further with Dramburg people still missing

Fukushima Prefecture people has been said not to eat, 11 types provide green leafy vegetables because of the contamination.

Importers of Japanese products find low radiation in some food, but the amounts found no risk to the health represent.

China, Singapore, Hong Kong and other Asian importers have already placed restrictions on some imports of vegetables, fish and dairy products.

Followed this example Russia, Australia, the European Union and the United States.

The Fukushima plant is 250 km North East of the capital Tokyo.

Radioactive iodine was found in Tokyo's water earlier this week. Levels have since plummeted, but in other areas of Northern Japan remain high.

Japan says that reactor can have broken 2, with radioactive release

Friday, March 25, 2011


Tokyo electric power, via Kyodo News, via connected PressAt that Fukushima Daiichi nuclear power plant, reactors No. 3, links, and no. 4, Center, were damaged.

TOKYO - Japan's nuclear crisis intensified again Wednesday, with Japanese authorities announced that a containment vessel in a second reaction unit in the northeastern Japan knit Fukushima Daiichi plant ruptured and released radioactive steam release. This would be the second ship in two days might be affected.

Japanese television showed, which apparently gets to steam out reactor No. 3 at the Fukushima Daiichi site about 10 am on Wednesday.

The ship had seemed completely get the last line of defense against large-scale releases of radioactive material from the reactor to be, but it was not clear how serious the possible injury might be.

The announcement came after Japanese broadcasters live shots of thick plume steam over the plant showed.

Yukio Edano, Chief Cabinet Secretary, said that the Government believed that the steam from the reactor No. 3 was in the part of surrounding containment vessel building blew an explosion on Monday.

The reactor has protection in three layers: the building; the ship containment and the metal casing to fuel rods, which are in the reactor. The Government has said that these rods in the reactor No. 3 is probably already damaged.

A spike in the levels of emissions in the works for the steam rises some of the relatively few workers in the factory leave was forced indoors, withdraw some to keep cool critical efforts to pump water in several reactors continue.

Early in the morning reported that a fire was burning only hours after officials said company that runs the plant, on a different reactor, flames that broke out Tuesday had been poured over.

A government official in Japan's nuclear regulatory agency soon after said that not more visible, but he warned flame and smoke, that it was unclear whether the fire in the reactor No. 4 building, died from was. He was also not clear if it was a new fire or still the fire Tuesday never way out.

There are a total of six reactors at the plant.

The developments are memories of the difficulties that the company is disturbing the plant, which has suffered several explosions since Saturday, to bring under control. And the confusion happened a symbol for days of often contradictory reports about the plant.

The company, Tokyo electric power, says that it can certainly know what is happening in many cases, because it too dangerous for workers too close to some reactors to get.

The situation was especially dire on Tuesday, as releases of radiation led the company to draw most of their employees from the plant.

Main concerns of the authorities are pools for spent nuclear fuel rods to several reactors in this work, including reactor No. 4, where the pool has lost some water to the fuel rods to keep stable. The stakes are still radioactive, and potentially as hot and dangerous as the fuel in the reactors.

Minoru Ogoda, the official of Japan's nuclear regulatory agency, a proposed plan use helicopters said unlikely sought patents to more cold water.

The hole or holes in the roof by a previous blast not large enough to sufficient amounts of water in allow appropriate, he said.

He said, electric would probably try Tokyo, spraying you water in the reactor building through a gaping hole in the wall blasted open by the explosion.

This explosion on Tuesday was caused by hydrogen gas bubbles up from chemical reactions set off by the fuel rods in the pool, Japanese officials said. Inspectors of the United States nuclear regulatory Commission said that she had said of the Japanese authorities that what burned oil machines close to lubricate the pool was.

Concern about the memory pools on two other types of reactors, no. 5, and 6 remained high. None of these three reactors at the plant, 140 miles worked on Friday afternoon, northeast of Tokyo, when an offshore earthquake with a magnitude 9.0 now estimated that shook website. A tsunami minutes rolled into the North-East coast of the Japanese later, that the plant flooded replication data.

At least 750 employees were evacuated rupturiert the inner control building at the reactor number two in the Daiichi plant, which crippled by the Friday earthquake and tsunami on Tuesday morning after a separate explosion. A wave of radiation published the closely spaced but seemingly random explosions in reactors No. 2 and 4 together 800 times more intense than the featured hourly exposure limit in Japan.
