United States once dropped 67 nuclear bombs in the island, still live-bomb, island-IT information
More than 60 years ago, the United States had in the Marshall Islands (Marshall Islands) dropped dozens of bombs. Today, residents of this small island nation are still unable to return to their homes.
Colombia University recently in the United States National Academy of Sciences (Proceedings of the National Academy of Sciences) published study said radiation levels remained close to human habitation in the Marshall Islands twice times the safe level.
From 1946 to 1958, United States conducted 67 nuclear weapons tests in the Marshall Islands. The Marshall Islands is a chain of atolls in the Pacific, only 52,000 population of the country.
United States most famous test of a nuclear weapon "death blow" (Bravo shot) is 1954 at Bikini Atoll (Bikini Atoll) on the. The test explosions equivalent is 1000 times times the Hiroshima bomb. Local residents had to move to other places, where no one has lived .
Researchers found that radiation on Bikini Atoll 184 millirem per year (millirems) radiation. This value is the United States and the Marshall Islands to develop safety standards (100 millirem) twice. Some areas of radiation even a whopping 639 millirem.
According to the Science News (Science News) reported that scientists had predicted years of Bikini Atoll level will be reduced to 16 millirem a year, which means radiation duration longer than here.
But Marshall still had a glimmer of hope, apart from the outside in a bikini Island, island of five other emissions are below the safety standard of 100 millirem per year.
Colombia may help a lot to move elsewhere at the University of the Marshallese people prepare to return to their homes. At present, almost half of the country's population lives in the capital Majuro (Majuro) downtown. Due to rising sea levels could inundate the entire archipelago of risk, Marshall is becoming more and more crowded.
United States nuclear tests was still Marshall one indelible memory, officials also strive for nuclear reduction of the world constantly. In March this year, Marshall Islands symbolically sued the United Kingdom, and India and Pakistan, and urged those countries to eliminate nuclear arsenals.
Meanwhile, Marshall, immigrants and their descendants in the United States find a home, particularly Honolulu (Honolulu) and Kansas spring Dyer (Springdale) Marshallese communities is growing.
Scientists said that more testing was needed to determine the island's food and water supplies are safe and livable.
美国曾在这个岛上投下67颗核弹，至今无法居住 - 核弹,岛国 - IT资讯
60多年前，美国曾在马绍尔群岛（Marshall Islands）投下数十颗核弹。时至今日，这个小岛国的居民们仍旧无法返回自己的家园。
哥伦比亚大学近日在《美国科学院学报》（Proceedings of the National Academy of Sciences）发表的研究称，马绍尔群岛的核辐射水平仍旧接近人类居住安全水平的两倍。
1946年至1958年间，美国在马绍尔群岛进行了67次核武器试验。马绍尔群岛是太平洋中的一串环状珊瑚岛，这个国家只有5.2万人口。
美国最著名的一次核武器试验“致命一击”（Bravo shot）就是1954年在比基尼环礁（Bikini Atoll）上进行的。这次试爆的当量是广岛原子弹的1000倍。当地居民不得不迁居其它地方，这里至今无人居住。
研究者发现，比基尼环礁上的放射性物质每年会产生184毫雷姆（millirems）的辐射量。这一数值几乎是美国与马绍尔群岛制定的安全标准（100毫雷姆）的两倍。有些地区的年辐射量甚至高达惊人的639毫雷姆。
据《科学新闻》（Science News）报道，科学家曾预测比基尼环礁的年放射水平将会降低至每年16毫雷姆，这意味着此地辐射持续时间比想象的更长。
不过马绍尔人仍旧有一丝希望，除比基尼岛礁外，其它五个岛的放射量都低于每年100毫雷姆的安全标准。
哥伦比亚大学的研究可能帮助很多移居他处的马绍尔人为重返家园做好准备。目前，这个国家近乎一半的人口都住在首都马朱罗（Majuro）主城区。由于不断上升的海平线有可能会淹没整个群岛的风险，马绍尔正变得越来越拥挤。
美国核试验仍旧是马绍尔人心中不可磨灭的记忆，官员们也在为世界核裁减不断奋斗。今年3月，马绍尔群岛共和国象征性地起诉了英国、印度和巴基斯坦，敦促这些国家消除核武器库。
与此同时，马绍尔移民及其后代也在美国找到归宿，尤其是火奴鲁鲁（Honolulu）和堪萨斯斯普林代尔（Springdale）的马绍尔人社区正在发展壮大。
科学家们表示，还需要进行更多测试来确定各岛的食物和水源是否适合安全宜居。
