美国27个核电站泄漏 地下水源被污染

北京时间2010年2月3日,据美国媒体报道,美国核管理委员会2月1日宣布,美国东北部的佛蒙特州扬基核电站发生氚泄漏事件。报道称,由于地下管道老化,目前美国至少27个核电站发生过氚泄漏事故,周围地下水源被污染。

氚元素含量超标3倍

美国核管理委员会2月1日说,从佛蒙特州扬基核电站监测井中抽取的最新地下水样本显示,水中氚元素含量是联邦安全标准的3倍多。

报道说,该核电站负责人承认以前对州政府和监管人员隐瞒真相,说核电站不存在可能发生氚泄漏的地下管道,上个月早些时候在监测井中测出的氚含量不足以对人体健康构成威胁。对此,佛蒙特州州长吉姆·道格拉斯严厉谴责核电站的欺骗行径,称这是不可容忍的。

氚是一种放射性物质,在自然界中十分稀有。它的性质与氢相似,主要用于热核反应。少量接触不会对人体有害,但如果大量吸入就会导致癌症。

According to U.S. media reports,the United States Nuclear Regulatory Commission February 1 announced that the U.S. northeastern state of Vermont Yankee Nuclear Power Plant tritium leaks occurred. Reported that,due to the aging underground pipes,the current U.S. nuclear power plants for at least 27 spills of tritium occurred in the surrounding underground water sources are contaminated。

Tritium levels exceeding three times the

U.S. Nuclear Regulatory Commission on February 1 that from the Vermont Yankee nuclear power plant monitoring wells most recent groundwater samples collected show the water tritium concentrations of the federal safety standard three times more。

Reported that the nuclear power plant officials recognized that the previous state government and regulators to conceal the truth,saying that there is no nuclear power station tritium leaks that may occur underground pipeline earlier this month in the monitoring wells measured tritium concentration not sufficient to pose a human health threat。 In this regard, Vermont Governor Jim Douglas,condemned the deceptive acts of nuclear power plants,saying it is intolerable。

Tritium is a radioactive substance,is very rare in nature。It is similar to the nature and hydrogen is mainly used in thermonuclear reaction。 A small amount of exposure is not harmful,but if a large number of inhaled can lead to cancer。
