IAEA worried about radiation in Japan village

Antwerp steps up radioactivity checks on ships from Japan
Brussels (AFP) March 30, 2011 - Antwerp has stepped up checks on ships that have sailed in the vicinity of Japan to avert the risk of radioactive contamination from the stricken Fukushima nuclear plant, the Belgian port said Wednesday. Ships arriving in Antwerp, Europe's second largest port after Rotterdam in The Netherlands and among the world's 15 biggest, are required to present a list of the last 10 ports where they have called, the port authority said in a statement. "If one of these is a port in the Japan region, then the authorities may carry out additional onboard measurements to check for radioactivity. If any abnormal readings are found, then the ships will be further monitored by FANC (Belgium's nuclear watchdog)," it said. The "extra precautions" are being taken "as a consequence of the nuclear disaster (in Fukushima)," it said.

They aim to eliminate "any risk to public health, both for port personnel and persons in the surrounding area," the statement said, while stressing that "there is no cause for concern." Japanese goods transiting Antwerp "are mainly containers and cars" and make up a "relatively small" percentage of the port's total volume, the statement said. In addition, "all containers in the port are routinely scanned for radioactivity on a daily basis using the Megaports system," set up in the wake of the September 11, 2001, terror attacks on the United States, it said. Other European ports such as Hamburg, in northern Germany, have also taken precautionary measures with ships coming from Japanese waters, the Financial Times Deutschland reported Wednesday, notably after the Chinese port of Xiamen turned away a ship emitting higher than normal radioactivity readings last week. Japan has struggled to contain its nuclear emergency since a massive tsunami hit the Fukushima plant after the March 11 earthquake, with radioactive substances entering the air, sea and foodstuffs from the region.

Vienna (AFP) March 30, 2011
Radiation levels recorded at a village outside the evacuation zone around the quake-striken Fukushima nuclear plant are above safe levels, the UN atomic watchdog said Wednesday.

The International Atomic Energy Agency said safe limits had been exceeded at Iitate village, 40 kilometres (25 miles) northwest of Fukushima, well outside the government-imposed 20 kilometre exclusion zone and the 30-kilometre "stay indoors" zone.

"The first assessment indicates that one of the IAEA operational criteria for evacuation is exceeded in Iitate village," the IAEA's head of nuclear safety and security, Denis Flory, told reporters here.

The watchdog had advised Japanese authorities to "carefully assess the situation and they have indicated that it is already under assessment," Flory said.

But he said the IAEA -- which does not have the mandate to order national authorities to act -- was not calling for a general widening of the exclusion zone.

Iitate lies 40 kilometres (25 miles) northwest of the Fukushima nuclear power plant, which was crippled by a tsunami on March 11 and several explosions, leading to frantic efforts to prevent a catastrophic meltdown.

Advice had been given to "carefully assess the situation and they have indicated that it is already under assessment," he said.

The reading in Iitate was merely a spot reading, he said.

"Deposition of radioactivity is something which is not the same everywhere, it depends on wind, it depends on rain and also on profile of terrain," Flory said.

"Saying at one point that there is a need to assess further does not mean that all around that is a concern."

But he said that overall, the situation at Fukushima "remains very serious."

According to Elena Buglova, head of the IAEA's Incident and Emergency Centre, the reading in Iitate village was 2 megabecquerels per square metre.

That was a "ratio about two times higher than levels" at which the agency recommends evacuations, she explained.

Radiation levels soar in sea near nuclear plant
Osaka (AFP) March 30, 2011 - Radiation levels in the sea off Japan's stricken nuclear plant hit their highest reading yet, officials said Wednesday, amid a struggle to deal with large amounts of radioactive water at the site.

A spokesman for Tokyo Electric Power Co., operator of the Fukushima Daiichi nuclear plant crippled by a March 11 earthquake and tsunami, said levels of radioactive iodine-131 were 3,355 times the legal limit in the sea near the plant, according to a reading taken Tuesday.

Officials said they did not know what cause the radiation level to rise.

"The figures are rising further. We need to find out as quickly as possible the causes and to stop them from rising any higher," said nuclear safety agency spokesman Hidehiko Nishiyama.

The sampling location is 330 metres south of the discharge outlet for four troubled reactors. Officials have said that tidal dispersion means that there is no immediate health threat, and that the iodine degrades relatively quickly.

A 9.0 magnitude earthquake and tsunami knocked out the cooling systems of the Fukushima plant's six reactors -- triggering explosions and fires, releasing radiation and sparking global fears of a widening disaster.

Radiation from the plant northeast of Tokyo has wafted into the air, contaminating farm produce and drinking water, and seeped into the Pacific Ocean.

In a stop-gap measure to contain the crisis at the plant, crews have poured thousands of tons of water onto reactors where fuel rods are thought to have partially melted, and topped up pools for spent fuel rods.

But the run-off of the operation has accumulated in the basements of turbine rooms connected to three reactors and filled up tunnels, making it too risky for workers to go near to repair cooling systems needed to stabilise the plant.

The water out of reactor two has measured 1,000 millisieverts per hour -- four times the recently-hiked total exposure limit for emergency staff, and a level that can cause radiation sickness with nausea and vomiting in an hour.

On Sunday, iodine-131 measuring 1,850 times the legal maximum were reported a few hundred metres (yards) from the plant, up from 1,250 times the limit Saturday.

Japan's government has evacuated hundreds of thousands of people from within 20 kilometres of the plant, and more recently encouraged those remaining within 30 kilometres to also leave.

Anti-radiation resin to coat Japan plant grounds
Osaka (AFP) March 30, 2011
Workers at Japan's stricken Fukushima nuclear power plant plan to spray its grounds with a special resin to prevent further radioactivity being released, a nuclear safety agency official said Wednesday. Faced with an unprecedented crisis, authorities are grappling to control four crippled reactors that have been leaking dangerous radiation after a March 11 earthquake and tsunami knocked out ... read more
