1、Countries across Asia and beyond are reporting small amounts of radiation from the disabled nuclear reactors in Japan. 亚洲和亚洲以外的国家都报道来自日本受损的核反应堆的少量放射性物质。 Beyond： prep. 超过；越过；那一边；在.较远的一边 adv. 在远处；在更远处 n. 远处 reactor rikt 反应堆,But officials say these levels are not a threat to public health 。但是官员们表示，放射性物

2、质的含量很低，不会对公众健康造成威胁。 On Tuesday, Chinese officials reported low levels of radioactive iodine-131 in areas of southeastern China.周二，中国官员报道东南地区出现低水平的放射性同位素碘131。 These include Guangxi, Guangdong and Shanghai. Earlier tests found the material in the northeastern province of Heilongjiang. 包括广东，广西和上海。此前的检测

3、已经发现东北省份黑龙江出现这种放射性物质。,In South Korea, nuclear safety officials say they have found radioactive iodine in Seoul and several other areas. 在韩国，核安全官员表示，他们在首尔和其他几个地区发现了放射性碘。 Nuclear：nju:kli原子能的 ，原子核的,Traces from the Fukushima power station have also been found as far away as Britain and the eastern Unite

4、d States. 英国和美国东部也发现了来自福岛核电站的极少量放射性物质。 trace treis ： n. 痕迹，踪迹；微量；仪 迹线；缰绳 vi. 追溯；沿路走 as far away as：远的,Radioactive iodine loses half its strength in a week. But a more dangerous material, plutonium, has also been found in soil near the power plant. 一周之内，放射性碘的威力已经减少了一半。但是核电站附近的土壤中发现了一种更加危险的物质钚。 materi

5、al mtiril ：n. 材料，原料；物资；布料 plant plnt ：n. 工厂，车间；植物；庄稼；设备 vt. 安置；种植；栽培；培养,Some medicines, like Prussian blue pills, can help expel radioactive elements from the body.

6、spu ：n. 暴露；曝光；陈列；揭露,The best known is potassium iodide. The pills flood the thyroid gland with non-radioactive iodine. The thyroid gland is a small organ in the neck that requires iodine for good health. 最广为人知的就是碘化钾。这种药片可以使非放射性的碘涌入甲状腺。甲状腺是脖子里一个很小的器官，需要碘元素来维持身体健康。 thyroid airid ：甲状腺,But people expose

7、d to high levels of radioactive iodine can get thyroid cancer. The pills block the thyroid from absorbing radioactive iodine and reduce the cancer risk. 但是，暴露在高水平的放射性碘中的人可能会患甲状腺癌。这种药片可以阻止甲状腺吸收放射性碘，降低癌症风险。 block blk vt. 阻止；限制 n. 块；街区；大厦；障碍物 absorb bz:b vt. 吸收；吸引；承受；理解；使全神贯注 But, it really can absorb

8、in radiation. 但是，它真的能吸收辐射啊。,But the pills are not a cure for radiation sickness. And they work only if the radioactive iodine has been taken into the body through food or drink 。 但是这种药片不能治疗辐射造成的疾病。而且只有在放射性碘通过食物或水进入体内的情况下才能发挥效用。 only if ：只要就；只是在的时候 But that held true only if the demand for money was
