With the rise of radio technology, people are increasingly exposed to electromagnetic radiation. And among the physical development factors leading to cancer, the factor of electromagnetic radiation is getting more and more attention. There are many facilities that generate electromagnetic radiation, such as large radio and TV towers, military radar, high-voltage power lines, etc., and small ones such as TV sets and microwave ovens. Briefly introduce the two commonly used appliances: 1, microwave ovens microwave ovens use a non-ionizing radiation energy, its damage effect than the ionizing radiation energy of X-rays much smaller. However, animal tests have shown that non-ionizing high radiation energy can also seriously damage various tissues. The greatest danger of early microwave ovens was the leakage of excessive radiation energy. Now, some manufacturers are marking the radiation safety factor on the machine . If the radiation level is below the safety factor, you will not be harmed by the radiation when you operate it. Terminal displays also release low frequency non-ionizing radiation, but this type of radiation does not cause cancer or blood disorders. 2, TV TV display terminals are present in almost every modern office. Ionizing radiation and non-ionizing radiation from TV displays affect human health. People who use it regularly can suffer from eye damage. Ionizing radiation from TV terminal displays (a potential carcinogen) is extremely harmful and emits almost no harmful rays in a normal operating environment. Home appliances work by emitting electromagnetic waves of different powers to the surrounding area, i.e. electromagnetic radiation. Long-term human exposure to electromagnetic radiation and reach a certain dose, will produce biological effects, damage human health, suppress human immune function, and induce cancer or blood disease. In order to avoid the damage of electromagnetic radiation to the human body, to stay away from electromagnetic radiation sites, do not long-term in the radio and television towers, military radar and high-voltage lines near, home appliances do not place too concentrated, buy high-quality microwave ovens to prevent microwave leakage; watch TV to more than 3 meters away, etc..
