Uses: lethal radioactivity in Fukushima

Radiation is increasingly strong in central Japan's Fukushima, plunged into crisis after the earthquake and tsunami on Friday, and slow action to extinguish fires and to cool the hot reactor. 3 coverage in the reactor containment has cracks from which radioactive vapors vented, there are fears for the reactor 5 problems, because so far stayed out for months to work off. In the two reactors would cast 70% of the core and the surrounding area, warns the head of the Commission Gregory Jaczko U.S. nuclear and radiation are "deadly." It does not seem close to the positive solution of the nuclear drama that adds to the tragedy of the country shaken by the violent earthquake and killer wave - and powerful aftershocks yesterday.
Helicopters and drones
A big Chinook helicopter with two propellers that tried to throw water on the Central has had to surrender when the counters geyger in the cabin went crazy: the pilots were at risk of contamination. The United States today could take off a drone, an unmanned, to take photographs and measurements of the plant. The 800 employees of TEPCO stay away, and only a team of about fifty of them could get close to risk their lives to carry out operations on equipment.
U.S. and (especially) France
Yesterday I spoke remote controlled water cannon, while adding high-pressure pumps are worked by the U.S. and France's Areva and EdF have decided to send teams of experts. We must carefully monitor what he does in France (see also the article on the right), having the largest number of reactors (note: national technology) and perhaps has the most experience with the nuclear industry: in addition to 'sending of technical, France is competing with General Electric Hitachi technology put to the test in Fukushima and in recent days had already sent out notices warning to its citizens in Japan.
Fires
The hydrants are used to extinguish fires conventional occurred on the fourth floor of the building of reactors 3 and 4. Burn something in concrete tanks where they are protected and conserved the fuel rods from reactors already in use, the items "waste" of the atomic pile. We do not know what to burn, because fire is in the environments in the presence of combustible materials at zero degree, that there is nothing that can ignite. Meanwhile you continue to inject fresh sea water in buildings containing the kernels, to cool the reaction.
Clinton and Ottinger
"What is happening in Japan raises questions about the costs and risks associated with nuclear energy, but we need answers," he said yesterday, the Secretary of State Hillary Clinton. The U.S. Embassy in Tokyo has recommended to his fellow citizens to move away from a radius of 80 kilometers from the center. The European energy commissioner, Günther Ottinger, fears that "in the coming hours we run the risk of witnessing a new catastrophe" and the situation is "out of control."
Controversy Alitalia
The return of the Italians in Japan has been accompanied by accusations of many travelers against Alitalia for prices and quality service. In particular, there have been problems for the tour of the Maggio Musicale Fiorentino, whose chorus will complete the return today. Alitalia replied pointing out the reduced rates introduced in this tragic occasion.
The cost of tragedy
The devastation of the mega-earthquake in Japan and the nuclear crisis could lead, according to initial estimates by analysts, in an overall loss of up to $ 200 billion.
The radioactivity of Rome
Tokyo at the moment is not radiological in Rome. To say this is a report prepared by the Italian Civil Protection, according to a measurement made from the roof of our embassy in Japan. In Tokyo there are microsievert 0.04 per hour, while in Rome, the radioactivity of natural background is 0.25, six times. No fear: Most of Lazio and Campania - volcanic areas - have a more distinct natural radioactivity, which focuses more alarming in traditional houses built with tuff, rock impregnated with radon gas, radioactive.
