Radiation is divided into ionizing radiation and non-ionizing radiation. The energy generated by radiation depends on frequency, and the higher the frequency, the greater the energy. The energy of non-ionizing radiation is low enough to change the chemical properties of substances, so microwave ovens belong to non-ionizing radiation.
Microwave is an electromagnetic wave, which is essentially the same as radio waves, infrared rays and visible light used in radios and telegrams. The only difference between them is the frequency. The frequency of microwave is higher than that of electric wave and lower than that of infrared ray and visible light. Radio waves and visible light do not cause cancer, and microwaves with natural frequencies between them do not cause cancer.
Microwave energy will be converted into heat after being absorbed by food, which will not cause "radioactivity" or "pollution" to food.

The correct way to use the microwave oven: try to stay away from the microwave oven when using it, and try not to get too close to the microwave oven for pregnant women. Secondly, try to buy qualified microwave oven products to ensure that the products are not damaged and the microwave oven does not leak. Use the correct container to hold heated objects to avoid explosion.
The safety accidents of microwave ovens are often caused by improper use. The following two types of accidents are the most common:
1, liquid overheating. When microwave heating, because water does not flow, but the temperature rises, it may not open when it exceeds the boiling point, resulting in overheating. At this time, as long as the water is slightly disturbed, it will boil violently, which is prone to scald accidents. The cleaner the container and the cleaner the water, the greater the possibility of occurrence.
2. The egg exploded. The microwave oven can't heat the eggs, because overheating inside the eggs will generate more pressure, which may explode if it is released due to external interference.
