日本核泄漏污染物最快本周五抵达美国西海岸
中新社洛杉矶3月16日电 据《洛杉矶时报》报道，美国原子能专家指出，从日本核电站泄露的第一波放射性污染物最快将于本周五(18日)抵达美国加州等西海岸上空。不过专家认为，辐射物的含量在安全范围以内。
报道说，日本大地震和海啸引发核电站泄露事故后，世界各地和美国的检测网络密切监视核污染物的动向。 从日本核电站泄露的少量核辐射物正随高空气流飞跃太平洋飘向北美大陆。美国环保部管理的核辐射检测网络由100个检测站组成，该网络每天24小时不间断地 监控全美各地地核辐射情况，此外还有63个联合国“全面禁止核试验条约组织”管理的监测站在进行同样的工作。
美国专家说，来自日本的第一波核污染物最快将在本周五出现在美国西海岸上空，也有可能晚一周左右抵达。以加州南部的洛杉矶为例，距离日本福岛大约有8000公里。专家说，2006年朝鲜进行核试验时，大约两周后核辐射物到达美国西海岸上空。
美国原子能管理委员会专家今天表示，抵达美国夏威夷、阿拉斯加、西海岸的核辐射物不会达到危险水平，不过第一波核污染物过后，美国上空的核辐射物含量很可能会升高，因为日本核电站核泄漏事故在加剧。该委员会已经要求在日本核电站周边80公里范围内的美国公民迅速撤离。

美国原子能管理委员会的电脑模拟显示，在福岛第一核电站周围半英里范围内，核辐射水平之高足以致命， 即使是80公里处的辐射剂量也超过每人每年正常接收的辐射量的16倍。不过专家也指出，即使日本核泄漏物在增加，但辐射物在抵达美国上空时已经被大气层冲 散，浓度会大幅下降。
报道最后提到，一个不容乐观的情况是，福岛核电站的第三号反应堆使用的是核燃料钚，这是一种对人类健康极度危险的放射性物质，即使是微小的剂量也会导致严重后果。(完)
UN: Nuclear plume may reach US by Friday

As Obama orders the evacuation of American personnel from Japan, the UN predicted a nuclear plume generated in Japan could cross the pacific and hit the west coast of the United States as soon as March 18.
Thousands are descending on Japan’s airports fighting to get out of the county as more nations begin to advise their people to evacuate.
Attempts by scientists and the Japanese military continue to fail to keep the reactors under control, some even warning Japan may have only 48 hours to avoid a Chernobyl like disaster.
The UN's Comprehensive Test Ban Treaty Organization issued a statement alleging a radioactive plume could hit California by March 18, and soon thereafter reach Nevada, Utah, Arizona and other western states. They did not indicate the level or severity of the radiation, but pointed out the levels would dissipate as the plume traveled from Japan across the pacific.
The projection is calculated based on predicted wind patterns, and could easily change and travel in other directions, or travel even further in the same direction. It also assumes certain reactors have failed and a greater leak of radiation may be imminent.
Emergency workers are technicians are actively working to keep the reactors cool in order to prevent further disasters, but as the overheating cores continue to boil away water used as a coolant, it may be matter of time before catastrophe strikes.
In the United States health and nuclear officials, and President Obama himself have repeatedly said there would be no real threat of radiation from Japan. In addition, he has ordered a number of Americans working in the area on the crisis be recalled and other US personnel evacuated. Travel warnings by the US government now insist American tourist leave the country and delay or cancel any future travel plans to Japan.
The Japanese government continues to insist the problem is under control and will be solved. However Obama’s recent decisions have many questioning the reliability of the information coming from the Japanese government.
Radiation Plume Could Reach US By Friday: 5 Ways To Protect Yourself
Nuclear reactors damaged by the recent earthquakes and tsunami in Japan could cause water-borne radiation plumes to reach the West Coast of the United States as early as Friday, according to predictions by the UN's Comprehensive Test Ban Treaty Organisation.
It's important to note that the UN, the United States Nuclear Regulatory Commission, and Japan agree that if radiation leakage is caught up in the ocean currents, it "will be diluted as it travels and, at worst, would have extremely minor health consequences in the United States, even if hints of it are ultimately detectable" (NY Times).
The Treaty Organisation released their predictions to member states on Tuesday, and based their report on weather and current patterns at that time. A shift in weather patterns over the next 24 hours could cause a change in course.
Nevertheless, this unfortunate crisis is far from played out. The next 24 - 48 hours are crucial in Japan's effort to stop the nuclear fuel rod meltdown. It is entirely unknown whether they will be successful in stopping it.
If you live in the western states or provinces of North America, it is extremely important to be prepared by taking the following actions:
1) Fuel up your vehicle(s) and be ready to hit the road for a possible evacuation (or hunker down if you're out in the country and feel like you would be safer there).
2) If you plan to stay put, use plastic and duct tape to seal up your windows and doors. This will help protect you from radioactive fallout in the event of a total meltdown.
3) If you plan to evacuate, have a "Go Bag" ready to go at a moment's notice. This go bag should include a water filter, emergency radio, flashlight, duct tape, emergency knife, spare cash, whatever medical supplies you might need, extra food and water, spare fuel cans and so on.
4) Significantly increase your intake of iodine-containing foods and superfoods starting right now: Seaweeds are a great source. Many stores in California and even Colorado are quickly selling out of all kelp and much of their green foods supplements because people want to counter the effects of radiation naturally.
5) If you have potassium iodide pills (radiation pills), don't take them yet. Keep them ready to take if and only if a meltdown event occurs and a massive dose of radiation has been released into the atmosphere.
