Many people believe that eating iodine-rich foods including kelp, seaweed, shellfish and fresh fish can reduce the hazards of radiation. The true fact is that nuclear radiation is not equal to power radiation or electromagnetic radiation.
Radiation can be divided into many types such as nuclear radiation, belongs to radioactive radiation, and electro radiation, electromagnetic radiation, which is different to nuclear radiation and their mechanism on body are also different. Iodine, which is used for nuclear radiation protection, should be taken after required estimation by professionals.
In daily life, radiation released by electrical appliances such as electro radiation and electromagnetic radiation belongs to exterior radiation, which does not exist once cut off the electricity. Generally, electronic equipments in public places are insufficient to cause harm to humans.
However, the room where places many electrical equipments together should be ventilated frequently. Electromagnetic radiation will cause a change on molecules in the air to produce harmful substances such as free radicals, which causes damage to the body. By ventilation, harmful substances such as free radicals can be diluted or dispersed.
Of course, seafoods such as kelp and seaweed are rich in iodine, which is an indispensable part of daily diet to keep balanced diet. We should not only stare on the radiation.
