No health hazard traces of plutonium in Fukushima

Workers discovered more deposits of radioactive water is leaking from the damaged Japanese nuclear complex, officials said the plant, while emergency crews struggled to remove hundreds of tons of contaminated water and put the facility under control again. Officials believe the contaminated water has high levels of radioactivity in the coastal resort and has polluted the sea water and soil.

Workers found traces of plutonium in the ground outside the complex, but officials said there was no threat to public health. Japanese Prime Minister, Naoto Kan, said his government was "high alert" to address the problems of the troubled nuclear power plant in Fukushima. Plutonium is present in the fuel complex, which has been leaking radiation for more than two weeks, so the experts predicted it detect anything.

Contaminated water has been emitting more radiation than four times the limit that the Government considers safe for workers. People who worked in the place at that time were not affected, TEPCO spokesman Takashi Kurita. It is not known precisely where it comes from the water, but many suspect escapes from a damaged reactor.

The tsunami killed the system that cools the fuel rods, which are dangerously hot and has since been emitting radioactivity. Experts believe that the plutonium could come either from the atmosphere or spent fuel pellets in Fukushima, or damage to the reactor number three, the only one using plutonium as fuel.

The body of UN nuclear watchdog, the International Atomic Energy Agency (IAEA), said the finding was expected due to degradation of fuel known. The UN agency called for a summit, possibly in June, to coordinate the international response to growing concerns about nuclear safety following the crisis in Japan.

After the earthquake of nine degrees on the Richter scale and a tsunami. The Government of Japan also accounted for 17 thousand 258 people missing in the country and 18 000 houses destroyed and more than 130 000 buildings damaged. Rain falling in Northeastern states such as Massachusetts, Pennsylvania or Virginia carries a small sample of radiation from the stricken nuclear power plant in Fukushima (Japan).

The health departments of these states have issued alerts that warn their citizens not to drink the rainwater, but they insist that tap water is not contaminated and that the radioactivity levels are minimal and do not pose any public health hazard. Canadian scientists said they detected increased levels of radiation from Japanese nuclear power plant in Fukushima rain and algae from the Pacific coast of Canada.

The scientist said Kris Starosta iodine-131 has been detected but the levels found "pose no imminent harm to the public." This element emits radiation whose main use is the doctor (for radioactive iodine therapy for thyroid cancer). Large earthquakes in the past 30 years have triggered massive global chains of seismic activity, U.S.

researchers reported. But other large earthquakes trigger other large near and far smaller. The reassuring news for California and other earthquake prone areas where people wondered if the current movement of 9.0 that struck Japan could accelerate problems outside the region. Scientists at the U.S.

Geological Survey (USGS, in English) and the University of Texas at El Paso studied whether earthquakes of magnitude seven or greater intensity of movements were followed by five larger scale in other parts of the world. "Based on the evidence we have seen in our research, we believe that groups of large global earthquakes are more than a coincidence," he said in a statement Tom Parsons, a geophysicist at the USGS and author of a study appearing in the journal Nature Geoscience.

Large earthquakes were noticed at a distance of twice the length of the failure of a large quake, although it could generate smaller earthquakes at great distances, he said.
