For instance, because it takes only 8 days for the radioactive isotope iodine-131 to decay away to half its original level of radioactivity, simply waiting should be a fix.

例如，碘- 131的放射性只需要八天就衰减到它原来的一半，所以只需要等一等问题就能解决。

These cancers can be prevented if children are given pills containing the non-radioactive isotope of iodine soon after exposure.

这些癌症其实是可以避免的，只要在受到辐射之后，马上给儿童们服用不具有放射性的碘的同位素做成的药片。

Taking the pills effectively fills the thyroid gland with enough iodine to prevent the gland from absorbing radioactive iodine, a harmful isotope emitted from a nuclear reactor.

服下碘片可以使得甲状腺充满足够多的碘元素，从而能够防止甲状腺吸收核反应堆泄露的辐射性的碘。

Ingestion of the short-lived isotope iodine-131, with its well-known risk of thyroid cancer when absorbed in the thyroid glands of children and young people, was the only major radiation-related health effect of the Chernobyl accident on the public.
