These rays are emitted during the decay of certain versions of uranium, iodine, cesium and other elements.

距电厂西北二十五公里范围内少数村庄发现高浓度铯137。

Very high concentrations of cesium 137 were found near the village of Iitate, 25 miles northwest of the plant.

意味着健康威胁的主要的放射性核素包括放射性铯和放射性碘。

The main radionuclides representing health risk are radioactive caesium and radioactive iodine.

之前放射性的碘、铯的释放表明至少一个反应堆堆芯已被释放。

Previous releases of radioactive iodine and caesium had shown that material from the core of at least one reactor has been released.

该结构说，一旦在环境中扩散，铯-137“就是无法避免的。”

Once dispersed in the environment, it says, cesium-137 “is impossible to avoid.

放射性铯元素在福岛的花椰菜中被发现，大大超出国家限制范围。

在日本报道的放射性物质泄漏中，最令人担忧的主要是放射性碘和铯。

The big worries on the reported releases of radioactive material in Japan center on radioactive iodine and cesium.

铯137的放射可以打乱细胞运作，包括染色体，从而加大患癌风险。

The radiation from cesium-137 can throw cellular machinery out of order, including the chromosomes, leading to an increased risk of cancer.

The researchers used a focused beam of caesium ions to dislodge molecules of water from the inclusions and measured the amount with a mass spectrometer.

其中一个样品中还检测到了放射性的铯-137，但是还在法律限定标准之下。

Radioactive caesium-137 also appeared in one of the samples, but at levels below the legal limit.

目前第一层屏障，也就是燃料包层，明显已经失败了因为他们已经检测到了铯。

So far the first barrier, which is the fuel cladding, has apparently failed, because they are detecting cesium.

因此，放着在铯边上的盖革计数器的随机响声的间隔时间可以被用来产生随机数。

Thus the timing of the random ticks of a Geiger counter placed near the cesium might be used to generate random Numbers.

副产物包括反射性的碘和铯，它们会产生“衰变热”——即需要缓慢释放的残余热。

Those byproducts include radioactive iodine and caesium, both of which produce what's called "decay heat"--essentially residual heat that very slowly dissipates.
