- Radiation leaking directly into the air from stricken Fukushima nuclear plant
- Explosion at Number Two reactor follows blasts at One and Three
- Radiation levels rise around Tokyo – readings up to ten times higher than normal 15 miles from capital
- Fire breaks out at Number Four reactor
- Fears for residents yet to make it outside 19-mile exclusion zone
- Stock markets in chaos as Nikkei plummets 10.5% in one day
There was growing panic in Japan today as a third massive explosion and a fire at a nuclear power station hit by the tsunami pushed the country to the brink of catastrophe.
The government was forced to to order 140,000 residents to seal themselves indoors today as more radioactive material was released into the atmosphere by the third explosion at the plant in four days and the fire at another reactor.
Radioactive material is leaking ‘directly’ into the air from the stricken plant at a rate of 400 milliseverts per hour, according to The International Atomic Energy Agency. Anyone exposed to over 100 millisieverts a year risks cancer.
Radiation levels were rising around Tokyo this morning, with readings up to ten times higher than normal in Chiba – 15 miles from the capital.

It is another dramatic escalation in the nuclear crisis facing the country after Friday’s tsunami knocked out cooling systems at the Fukushima Dai-ichi plant – leaving engineers struggling to stop the reactors overheating and avoid a catastrophic meltdown.
It is the world’s most serious nuclear accident since the Chernobyl disaster in 1986.
All but 50 workers have been evacuated from the Fukushima plant, with the remaining employees frantically trying to keep pumping sea water into the reactors to cool them and control the fire. Although they have protective suits, they risk exposure to the dangerous levels of radiation.
In a televised address to the nation after the third explosion Japanese Prime Minister Naoto Kan confirmed radiation had been released into the atmosphere after blast at the Number Two reactor. The fire in the Number Four reactor was also said to be releasing radioactivity into the air.
It follows explosions at Number One and Number Three reactors.
The blaze in the spent fuel storage pond of Number Four reactor was put out today, but it was unclear if the radiation leak had been stopped.
There were also fears that the water inside the Number Four reactor may be boiling – which risks exposing nuclear fuel rods which in turn raises the risk of meltdown.
The exclusion zone around the reactor was extended to 19 miles this morning, and Chief Cabinet Secretary Yukio Edano told residents in the danger zone: ‘Please do not go outside. Please stay indoors. Please close windows and make your homes airtight .These are figures that potentially affect health. There is no mistake about that,’ he said.
Prime Minister Mr Kan added: ‘The possibility of further radioactive leakage is heightening. We are making every effort to prevent the leak from spreading. I know that people are very worried but I would like to ask you to act calmly.’
Some 70,000 people had already been evacuated from a 12-mile radius around the Dai-ichi complex. About 140,000 remain in the new warning zone.
Western news reporters are also evacuating the area.
The disaster has caused chaos in the financial markets, with the Tokyo Stock Exchange closing down 10.5 per cent.
Chief Cabinet Secretary Yukio Edano said: ‘Now we are talking about levels that can damage human health. These are readings taken near the area where we believe the releases are happening. Far away, the levels should be lower.’
Edano warned that there were signs that fuel rods were melting in all three reactors. ‘Although we cannot directly check it, it’s highly likely to be happening,’ he added.
Meanwhile, The French embassy in the capital warned in an advisory that a low level of radioactive wind could reach Tokyo within 10 hours.
Experts said the nightmare scenario was of a meltdown which triggers a massive build-up of pressure inside the containment unit. If the unit cracks, a plume of radioactive dust and gas would spill hundreds of miles into the air.
Fears of that meltdown at a Japanese power plant rose sharply last night after the third explosion was reported in the complex. It is thought the new drama occurred because the explosion in the Number 3 reactor had damaged the cooling system in the adjoining reactor, resulting in last night’s third blast.
Officials have been struggling to pacify the public’s concerns about radioactive material escaping into the atmosphere.
The Mayor of Fukushima City, Mr Tananori Seto warned of grave consequences for people who were living within a 20km range of the power station if they stepped out from their homes.
AMERICA ON RADIATION ALERT
There are growing fears that nuclear fall out from the Fukushima reactor could hit the United States.
Scientists warned yesterday of a ‘worst-case scenario’ in which the highly radioactive material could be blasted into the atmosphere and blown towards the West Coast by the Pacific jet stream – as seen in the graphic above.
They said it could be picked up by powerful 30,000ft winds, carrying the debris across the Pacific and hitting the West Coast. Some estimates claimed the radiation could arrive on America’s shores by this evening.
‘Right now it’s quite possible that there could be some radiation floating over the United States,’ said Nuclear Regulatory Commission spokesman David McIntyre.
He admitted that although evacuations had begun in the past two days, many people had remained in their homes – and now they were trapped there.
‘It is too dangerous to go outside and even if they did they would not be able to be transported to a safe place because we have no fuel for our vehicles,’ he said.
‘We need more information from the government. We aren’t getting enough information.’
Mr Seto said he hoped those who were still in their homes would keep a watch on their TVs and listen to their radios for updates.
‘Don’t even step outside to hang out your washing,’ he said. ‘If you’ve already done your washing, don’t bring it in from the line because it will be contaminated.’
People have been told to take showers if they think they have been contaminated but in many places there is no running water.
Water stored in outside tanks, officials warned, would be contaminated anyway.
With serious questions now surrounding the safety of the three crippled reactors, many people believe the chances of the material escaping have increased dramatically.
Workers at the crippled Fukushima nuclear power plant fled last night after a third explosion raised serious concerns about a meltdown.
Embarrassed officials of the Tokyo Electric Power company called a hurried news conference in Tokyo to apologise to the public for ‘the inconvenience’.
But they were hesitant in disclosing details about the full extent of the danger to the public.
In the House of Commons, David Cameron said he had ‘severe concerns’ for Britons who were in Japan at the time of the earthquake and tsunami. Thousands of them are still unaccounted for.
In a day of worrying developments:
- The official death toll rose to 2,800 but is expected eventually to exceed 10,000.
- Two thousand bodies were washed up in two towns in the worst affected area in north-east Japan.
- Strong aftershocks persisted in the stricken area, and a 4.1 magnitude earthquake jolted Tokyo at about 8pm British time yesterday.
- About 450,000 people have been evacuated nationwide – plus 180,000 from around the nuclear plant, where 190 have been exposed to some form of radiation.
- Almost 2million households are without power in the freezing north and about1.4million households have been left without running water.

Two other nuclear plants are also thought to be under threat. At Tokai there were also fears of overheating reactors as cooling pumps failed, while high levels of radiation were detected at the nuclear plant at Onagawa.
But the main concern remained the Fukushima plant on the north-east coast, where weary engineers were working around the clock for the fourth day.
Before last night’s third explosion they had been engaged in a last-ditch move to use seawater to cool the overheating core in reactor number two after fuel rods inside it were exposed.
Experts said it was probably the first time in the nuclear industry’s 57-year history that seawater, which is corrosive, has been used to cool fuel rods, a sign of how close Japan may be to a major accident.
Although the plant’s three working reactors shut down automatically when the magnitude nine earthquake struck, the cooling systems which keep the radioactive uranium and plutonium fuel rods cool have been hit by a series of failures.
Earlier yesterday a vast cloud of black smoke erupted from the plant after an explosion – the second in two days – demolished the building housing reactor three.
The explosion was triggered when engineers released steam to prevent a dangerous build-up of pressure inside the sealed reactor. At superheated temperatures inside the core the water vapour had split into hydrogen and oxygen which ignited, destroying the outer building and injuring 11 people, one seriously.
A similar explosion rocked the plant on Saturday when steam was released from another reactor.
Yesterday’s blast left the 80-inch concrete and steel walls which protect the nuclear reactor intact.

However, shortly after the explosion, the Tokyo Electric Power Company said it had lost the ability to cool the neighbouring reactor two – the third reactor to suffer cooling problems.
As the engineers tried to inject seawater using fire pumps the water levels dropped twice unexpectedly, leaving the fuel rods uncovered by cooling water. At one point they were exposed for two and a half hours.
Without coolant, fuel rods can overheat and melt. In a serious meltdown, radioactive molten material falls through the floor of the containment vessel into the ground underneath.
The drama at Fukushima has added to the anxiety for locals shellshocked by the quake and tsunami. Many Japanese are sceptical of assurances given by government officials about nuclear leaks, following at least two cover-ups in the wake of dramas in other plants in recent years.
Men in protective suits continued to sweep Geiger counters over terrified survivors, looking for evidence of radiation exposure.
After Japan’s request to the United States for help cooling the reactors, the U.S. Nuclear Regulatory Commission said it was considering providing technical advice.
President Barack Obama offered any help the U.S. could provide to help recover from its ‘multiple disasters’.
The U.S. Navy moved ships away from the devastated north-east Japanese coast after 17 helicopter crews helping in the rescue efforts were contaminated with radiation. The crews were treated on an aircraft carrier.
Scientists say there are serious dangers but little risk of a catastrophe similar to the 1986 blast in Chernobyl, where the reactor did not have a containment shell. Some said the length of time since the crisis began showed the chemical reactions inside the reactor were not moving quickly toward a complete meltdown.
Even so, the nuclear danger has prompted several countries to warn against travelling to and staying in Japan. In Britain, the Foreign Office advised against all non-essential travel to Tokyo and the north-east of Japan.
Disaster shows nuclear should be scrapped, say green groups
Green campaigners wasted no time in exploiting the disaster, claiming it proved nuclear power could never be safe.
Greenpeace warned that Japan faced a nuclear meltdown, while the Green Party called on the Coalition to scrap its nuclear programme.
Green Party leader and MP Caroline Lucas also called for an EU level inquiry into the wider implications of the nuclear accident.
Steve Campbell, of Greenpeace, said: ‘This proves once and for all that nuclear power cannot ever be safe. Japan’s nuclear plants were built with the latest technology, specifically to withstand natural disasters, yet we still face potential meltdown.’

Greenpeace was also concerned about the lack of data on the total amount of radiation already released, and whether the areas where spent radioactive fuel is dumped – outside the containment area of the reactor – were secure.
But nuclear scientists said the earthquake had highlighted how Japan’s power stations were robust.
Professor Paddy Regan, a nuclear physicist at Surrey University, said: ‘We had a doomsday earthquake in a country with 55 nuclear power stations and they all shut down perfectly, although three have had problems since.
‘This was a huge earthquake, and as a test of the resilience and robustness of nuclear plants it seems they have withstood the effects very well.’
Chris Huhne, the Energy and Climate Change Secretary, has ordered a review of the safety of the country’s nuclear reactors. The UK is poised to build a new generation of nuclear power stations over the next decade.
