来自伍兹霍尔海洋研究所的科学家在星期一表示，他们已经检测到源于2011年的福岛核危机的铯134的放射性沉降物，已经到达加利福尼亚北部100英里的Eureka小镇近海。

Scientists at the Woods Hole Oceanographic Institution on Monday said they had detected cesium 134 radioactive fallout from the 2011 Fukushima nuclear meltdown about 100 miles offshore of the Northern California town of Eureka .

针对核应急放射性沉降监测的特点，本文分析了地面剂量率监测和环境介质中的放射性活度浓度测量中存在的一些问题。

The paper discusses some problems in monitoring of dose rate and the measurement of mass radioactivity for radioactive fallout samples .

倘若低水平的辐射危害性低于预设，那么这些放射性沉降物很可能根本不会引起癌症患病率的增加。

If low levels of radiation are less harmful , then the fallout might not have caused any increase in the cancer rate .

像菠菜，生菜，韭菜等叶状蔬菜成长在室外，是最先被放射性沉降物污染的食物。

Leafy vegetables grown in the open like spinach , lettuce and leek are among the first foods to be tainted by radioactive deposits .

要比较放射性沉降物与疏散行动这两者的附加影响，依赖于“线性无阈值模型”的有效性，而该模型假定，任何剂量的辐射——哪怕它非常非常小——都会造成一定的危害。

How the added effect of the fallout would have compared with that of the evacuation depends on the validity of the " linear no-threshold model , " which assumes that any amount of radiation , no matter how small , causes some harm .

虽暂不必采取避难措施，但是在可能的情况下，应该避免不必要的接触到辐射物。特别是雨水，能将放射性微粒沉降到地面。

However , unnecessary exposure to radiation should be avoided when possible . Rain , in particular , can bring radioactive particles to the earth .
