The risk of microwave ovens lies in their heating capacity, but qualified microwave ovens will reduce the leakage of microwave energy through internal shielding devices. As long as it is not damaged in use, it will not leak microwaves that can harm the human body. And as long as the qualified plastic container marked "Microwave Heatable" is used safely, harmful components will not be released when heated.
The radiation in the microwave oven is very strong, which can make the objects with water and grease generate heat to cook food. However, the manufacturers of microwave ovens have taken safety measures and will not affect the human body. When using the microwave oven, people should stay away from the microwave oven or at least stay away from the microwave oven 1 m.
The essence of microwave is electromagnetic wave, which, like radio waves, infrared rays and visible light, will not cause cancer. On the contrary, infrared ray is a clinical therapy. In addition to not causing cancer to people, microwaves will not affect carcinogens in food, and even help to avoid carcinogens.
Extended data
Taboos for using microwave ovens are as follows:
1, avoid using ordinary plastic containers: hot food will deform plastic containers, and ordinary plastics will release toxic substances to pollute food and endanger human health.
2. Avoid using metal utensils: iron, aluminum, enamel and other utensils. When the microwave oven is heated, it will generate electric sparks and reflect microwaves, which will not only damage the furnace body, but also heat the food.
3. Avoid using a closed container with a narrow bottleneck: use a wide-mouth container when heating liquid, because the heat generated by food heating in the closed container is not easy to dissipate, so that the pressure in the container is too high and it is easy to cause blasting accidents.
4. Avoid overtime heating: food is thawed or heated in the microwave oven. If you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning. The heating time of microwave oven depends on the material and dosage, as well as the freshness and water content of food.
5. Avoid working in front of the microwave oven for a long time: After turning on the microwave oven, people should stay away from the microwave oven or at least 1 m away from the microwave oven.
