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 measuresThe 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.
Search further with Dramburg people still missingFukushima 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.
