Can iodized salt really prevent radiation?

Of course not. The public opinion peak of using iodized salt to prevent radiation in China is about 20 1 1 March. The "nuclear leakage" panic caused by the explosion of Japan's nuclear power plant spread throughout the country, and coastal cities such as Shaoxing, Ningbo and Fuzhou began to grab salt. Many residents flocked to supermarkets to buy salt to prepare for the nuclear radiation pollution in Japan. There are two reasons for grabbing salt: one is that eating iodized salt can prevent radiation, and the other is that nuclear leakage pollutes sea salt.

In fact, iodine is useful for radiation protection, but the iodine content in iodized salt is actually not much. Even though iodine has a little radiation protection effect, the iodine content in salt is very low. Potassium iodate in salt is different from potassium iodide in iodine tablets. Even if you eat a lot of salt, it won't have much radiation protection.

In an emergency, only iodine tablets can prevent radiation, but they must be taken under the guidance of public health experts and doctors. The general health department will issue an early warning when it finds nuclear pollution and other emergencies, and guide the public to take iodine tablets.

So I really don't need to blindly believe this rumor.
