In South Korea, nuclear safety officials say they have found radioactive iodine in Seoul and several other areas. 在韩国,核安全官员称,他们在首尔和其它几个地区发现了放射性碘(I-131)。
The water is contaminated with radioactive iodine and it's leaking into the sea. 这些水被放射性碘(I-131)污染,正在向海洋中泄漏。
But people exposed to high levels of radioactive iodine can get thyroid cancer. 但暴露于高水平的放射性碘(I-131)环境中会患上甲状腺癌。
The main radionuclides representing health risk are radioactive caesium and radioactive iodine. 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(I-131)。
Since radioactive iodine decays rapidly, virtually all radiation ceases within a few weeks. 由于放射性碘(I-131)能迅速破坏,因而实际上几星期内放射性就全部结束了。
