Peer drone in reactors of the Japan

Tokyo (cnn) - engineers used a drone to peer in reactors damaged at the nuclear plant of Fukushima Daiichi Sunday, as the crisis stimulated more than 2,000 people to March against nuclear energy in Tokyo.

"I was just a criticism of couch potatoes, but here we are today with friends for the first time, and I am sure that this is the first time today, for many people," said Karima Ley Stickanone of the demonstrators.

Monday marks a full month in the battle to avoid the worst disaster to Fukushima Daiichi, who was beaten by the earthquake and tsunami resulting that struck the North of the Japan on March 11. The Japan largest utility, Tokyo Electric Power Company, has been difficult to cool the three damaged reactors and prevent a wider dissemination of radioactivity that has already occurred.

Improvisation, frustration in fourth week of crisis

A camera was mounted on a helicopter remote to get photos of reactors damaged by high Sunday in the hope to get a better look damaged boxes No. 1, 3 and 4 reactors, and I hope that within the spent fuel poolsthe company spokesman Junichi Matsumoto said. The drone over the plant for 28 minutes at an altitude of approximately 150 metres (492 feet), he said.

The T-Hawk, built by the American company Honeywell, drone can send regular images and infrared images, Matsumoto told journalists. Images captured by the drone are expected to be released Monday, he said.

In addition, the company uses now controlled remotely from heavy machinery to remove the debris outside the factory and began the process of laying of new pipes to start pumping of radioactive water in the flooded basement of plant turbine behind 1-3 units.

Push in the area of radiation of the Japan

A worker fell ill while working on Sunday, the company said. The man, in his 30s, was placing pipes for the collection of the No. 2 reactor contaminated water when he fell ill, about two hours in his shift.

The subcontractor was taken to hospital, where he was diagnosed with exhaustion, said Tokyo Electric. It has been exposed to 4.82 millisieverts of radiation, but no radioactive substances were found on his body. His cumulative exposure is 16 millisieverts, well below the limit of 250-millisievert for factory workers. It was with a group of 30 subcontractors working in the field and wearing protective clothing, the company said.

The man had worked at four hours a day since 23 March, Tokyo Electric said. It was not clear whether he had received a day.

During this time, two world largest concrete pumps were en route to the Japan Sunday in the effort to help resolve the crisis.

Pumps left United States Saturday - Los Angeles and Atlanta, said Bill Dwyer, Vice President of sales and marketing for America Putzmeister, manufacturer of pumps.

Although the pumps were built to concrete pump, they can be modified to pump water at high pressure, with a 230-foot reach and "accuracy, locate" Dwyer said Sunday. "This allows workers to work at a greater distance," he said.

A pump is set to arrive Monday at the Japan and the second Tuesday, he said.

Workers have been pouring hundreds of tonnes of fresh water per day in three damaged reactors and pools of spent fuel from units 1-4 cool until normal traffic systems can be restored to keep them. The No. 2 reactor is supposed to be highly radioactive water leaks, of which some were spill in the Pacific until Wednesday, while the basements flooded in turbine of all plants are three units makes it impossible to restore powersociety representatives say.

To make room for the fluid, Tokyo Electric was dumping contaminated less water in the Pacific Ocean from a facility of waste on the site. This process, which also includes the release of radioactive water in river basins under reactors 5 and 6 - was almost full Sunday evening, nuclear and industrial safety agency of Japan reported.

Radioactive particles in the water are disperse in the ocean. But concentrations of iodine-131 radioactive remained 25 times higher than the Japanese legal standard in the sampled water 16 kilometers (10 miles) South of the plant on Saturday.

Is down 93 times the limit, on Wednesday, according to published Sunday data sampling. Levels of mingle cesium-137, which takes to lose half of its radioactivity of 30 years, has remained close to six times the limit legal but well below the levels reported earlier this week.

The landfill has been announced as an emergency measure, but it enraged the Japan fishing industry and drew protests from neighbour in South Korea. And participants in protest Sunday in the Shiba Park, at the foot of the Tower of Tokyo landmark, said concern over the effects of radioactive releases to date.

"Gets, the pollution of the air in the lungs,", said Dr. Nobuhiko Murapsu, a doctor of pulmonary care of Chiba Prefecture, North of Tokyo. "Five years, 10, 20 years later, they get lung cancer." This is a very severe problem. ?

Murapsu said that he has changed his views on nuclear energy since the accident and decided to join the demonstration. Demonstrators marched in the Park, surrounded by cherry blossoms, at the headquarters of Tokyo Electric and on the Ministry of economy, trade and industry, which governs the Japanese nuclear power plants.

Makiko Mikami told CNN that no one believes that they get enough responses of the utility or the Government.

"The problem is, I believe that I am not sure that they know the whole picture themselves," said Mikami. "" "". If they know, they should share this information with us. And if they do not, they should admit that they are so frightened. "Susan Olson and Yuki Arakawa contributed to this report for CNN
