8 NOW@SCIENCE之一：WHO：福岛核泄漏几乎未增加患癌几率已有1人参与

WHO: Fukushima Caused Minimal Cancer Risk
WHO：福岛核泄漏几乎未增加患癌几率

The World Health Organization (WHO) on 28 February released a report saying that the Fukushima nuclear disaster will cause no observable increases in cancer rates among residents of other countries and a very minimal increased risk of cancer among residents in the vicinity of the power plant. Workers who battled problems at the plant do face higher risks for some cancers. The WHO team estimated the increased lifetime risk of leukemia, thyroid cancer, and female breast cancer based on earlier estimates of radiation exposure in different locations around the power plant, which experienced multiple meltdowns and explosions in the aftermath of the 11 March 2011 earthquake and tsunami.

世界卫生组织（WHO）上月28号发布的一份报告中声称，福岛核泄露事故不会导致其它国家居民癌症患病几率明显的上升，而且核电站周边居民的癌症患病几率也几乎没有增加。然而当时处理泄漏事故的核电站工人患有某些癌症的几率会相对较高。WHO根据初步辐射暴露数据进行预估，发现一生当中患白血病，甲状腺癌和乳腺癌的几率会增加。这些初步数据来自核电站周围几个在2011年3月11日地震和海啸的余波中经历了多次核熔毁和泄露事故的地方。

Greenpeace condemned the report, stating that it “shamelessly downplays the impact of early radioactive releases from the Fukushima disaster on people inside the 20 km evacuation zone who were not able to leave the area quickly.” But Kazuo Sakai, a radiation biologist at Japan’s National Institute of Radiological Sciences, believes that the risks are overestimated, noting that the dose estimates used were based on preliminary data; actual measurements have shown the dose levels to be lower.

绿色和平组织谴责了这份报告，认为它“恬不知耻地把当时20公里疏散区内未能迅速撤离的居民受到的核辐射影响轻描淡写”。然而，日本国立辐射研究所的辐射生物学家Kazuo Sakai却认为是风险是被放大了。他指出，报告中使用的辐射剂量是之前的初步数据；实际测量的结果其实更低。
