The dangers of nuclear radiation and how to prevent it

　　The Japanese government has planned to distribute iodine tablets to residents living near the nuclear power plants as a means of protecting them from radiation from iodine-131. However, taking iodine supplements blindly can also cause harm to the human body. At a time when earthquakes, tsunamis, and nuclear radiation are all occurring simultaneously, we must also remain vigilant, learn proper emergency response measures, and take steps to prevent problems before they happen. Let’s learn together!

　　I. Iodine-131 may affect the thyroid gland disease

　　An explosion occurred at Unit 1 of the Fukushima Daiichi Nuclear Power Plant on the afternoon of the 12th. At a press conference on the 13th, Yukio Edano stated that at 1:52 local time, the radiation level near Unit 3 reached 1,557 microSiverts per hour, more than twice the permissible limit of 500 microSiverts per hour. However, this level dropped to 184 microSiverts 50 minutes later.

　　Hiroyuki Edano said that the radioactive substances detected so far around the nuclear power plant include iodine-131 and cesium-137. Iodine-131, once inhaled by the human body, may cause thyroid disorders. The Japanese government has planned to distribute iodine tablets to residents living near the nuclear power plants as a means of protecting them from radiation from iodine-131. Cesium-137 can affect the hematopoietic system and… nerve System damage.

　　Be careful when taking iodine tablets：

　　Although iodine can provide some protection against radiation, it should not be taken blindly. Excessive intake of iodine can lead to iodine-induced goiter and cause adverse effects; therefore, it is necessary to take iodine supplements in a scientific and reasonable manner under the guidance of a doctor.
