![]() America on nuclear alert: Could fallout from Japan explosion reach U.S. West Coast?
Fears that America could be hit by the nuclear fallout from the Japan earthquake dramatically increased today after the reactor hit by the tsunami went into 'meltdown'. Officials revealed fuel rods are melting inside three damaged reactors at the Fukushima plant, triggering fears of a serious radiation leak. Scientists in the U.S. warned today of a 'worst-case scenario' in which the highly radioactive material could be blasted into the atmosphere and blown towards the West Coast of America. They said it could be picked up by powerful 30,000ft winds, carrying the debris across the Pacific and hitting America within four days. Earthquake-hit Japan is fighting to avoid a nuclear catastrophe as one over-heating reactor lost its cooling today, following explosions at two other reactors at the Fukushima plant. Leading nuclear expert Dr John Large, who has visited the plant, said he is concerned that where the radiation ends up is ‘in the lap of the gods’. The exclusion zone keeps being raised. First it was 3km, then 10, now 20. This plant has gone through all the steps that occurred at Three Mile Island, and that led to total meltdown. ‘It looks like the reactors automatically shut down following the earthquake, causing a massive collapse of power to the grid,' he told the Sunday Express. Others have suggested any radioactive cloud would be likely to blow out east across the Pacific. 'The wind direction for the time being seems to point the (nuclear) pollution towards the Pacific,' Andre-Claude Lacoste, of the French Nuclear Safety Authority, told AFP. A second explosion rocked the nuclear plant today, sending smoke into the air. The blast follows a similar explosion in another unit on Saturday and a further reactor has also lost its cooling capacity. What would the reaction be if radiation from Japan reaches U.S. West Coast?If the radiation risk rises significantly, tablets could be distributed to prevent iodine-131 from being absorbed into the body. Radioactive particles, which attack or impair cells, can be taken into the body through breathing, eating or drinking. Atomic expert Dr Peter Weish said after Chernobyl that good practice for nuclear accidents includes sealing flats with adhesive tape, covering your mouth with a mask or wet cloth and having little contact with rain. California is watching Japan's efforts to contain leaks and looking at its own air, water and food supply - but public health officials said there is currently 'no danger'. But University of Washington Professor of Atmospheric Science Dan Jaffe told Q13 Fox earlier: 'Based on what we're seeing in terms of the radiation that's being released now, there is no risk at all. 'Even in the worst case scenario there is a low likelihood of much risk over the Pacific Northwest.' Nuclear regulators say the General Electric-designed reactors involved in the emergency are very similar to 23 reactors used in the U.S 'The worst case scenario is that the fuel rods fuse together,' nuclear expert Joe Cirincione said. 'The temperatures get so hot that they melt together into a radioactive molten mass that bursts through the containment mechanisms and it is exposed to the outside so there's spewed radioactivity into the ground, into the air and into the water,' he told Fox 43. 'Some of that radioactivity could carry in the atmosphere to the West Coast of the United States.' Rest of article |

![]() PLUME OF RADIATION
Gregory Jaczko, the top U.S. nuclear regulator, cast doubt on efforts to cool overheating reactors, saying workers may be hit with "lethal doses" of radiation. "It would be very difficult for emergency workers to get near the reactors," Jaczko said. A United Nations forecast projects the radioactive plume from the Fukushima facility would reach the Aleutian Islands on Thursday and hit Southern California late on Friday, The New York Times reported. The projection, calculated on Tuesday and obtained by the newspaper, gives no information about actual radiation levels, it said. Health and nuclear experts emphasize that radiation in the plume will be diluted as it travels and will have extremely minor health consequences in the United States, it reported. The U.S. military has ordered its forces to stay 50 miles away from the plant, the Pentagon said. There are at least 55,000 members of the U.S. forces in Japan and offshore assisting the relief operation. Rest of article |
