Potassium iodide pills are not "radiation antidotes". They do not protect against external radiation, or against any other radioactive substances besides radioactive iodine. They may also cause medical complications for some individuals such as persons with poorly functioning kidney and therefore taking potassium iodide should be started only when there is a clear public health recommendation to take this step.
钾片碘片都并非“核辐射解毒剂”。他们不能阻止外部的辐射、或是任何其他辐射形式。如果盲目服用,对某些人群甚至会造成副作用。比如肾脏功能不健全的人群就不适合服用。因而服用钾片碘片的举措必须在清楚的官方指示下进行。
