【世界核新闻网站2008年8月20日报道】美国核管会(NRC)2008年8月19日在其网站上表示,美国核工作人员在2007年的集体辐照剂量创历史新低。NRC表示,所有美国公民因宇宙射线、医疗和氡等辐射源照射而受到的平均剂量为3.6 mSv/a,美国104台核电机组工作人员最近几年的平均剂量仅在此基础上增加了1.6 mSv/a,而美国的职业辐照剂量限值为50 mSv/a。
[World Nuclear News website reported on August 20, 2008] The U.S. Nuclear Regulatory Commission (NRC) said on its website on August 19, 2008 that the collective exposure dose of nuclear personnel in the United States hit a record low in 2007. The NRC said that the average dose received by all U.S. citizens on exposure to radiation sources such as cosmic rays, medical radiation and radon is 3.6 mSv / a. The average dose of 104 nuclear power stations in the United States in recent years alone increased by 1.6 mSv / a, while the occupational exposure dose in the United States is limited to 50 mSv / a.
