The microwave frequency of domestic microwave oven is 2450 MHz. This kind of microwave can't penetrate the human body and harm the internal organs and tissues, but only heat the skin and body surface tissues. As long as the duration is not long, it will generally not cause harm to health.
Scientists have found that when the microwave leaked from the microwave oven propagates in space, its depletion degree is roughly inversely proportional to the square of the distance from the microwave oven. That is to say, if the microwave oven leaks 10 MW per square centimeter at the oven door, the space outside 1 meter is only 0.005438+0 MW. What's more, the actual leakage of microwave oven door is much lower than this value. International standards strictly stipulate that the microwave leakage of microwave ovens should not be greater than 5 milliwatts per square centimeter. The technical requirements of some domestic manufacturers are controlled within 1/5 of the international standard, that is, 1 milliwatt per square centimeter, which is 1/50 leaked from the international standard. Every microwave oven has passed the strict inspection of every manufacturing process to ensure that the microwave oven does not leak air. The door of the microwave oven is specially designed with multiple safety protection devices. When the door is opened during use, the microwave oven will stop emitting immediately to ensure the safety of users.
Use imported original microwave ovens: the safe distance for adults is 3-5 meters, and the safe distance for pregnant women is 5- 10 meters.
Use the household microwave oven: the safe distance for adults is 5 5- 10/0m, and the safe distance for pregnant women is10m.
The above refers to the distance that people who often use microwave ovens can get along safely for a long time because of microwave leakage. Children and pregnant women should pay special attention to keeping a distance of 5- 10 meters.
Note: This is only a safe distance for testing. It can't be that far in real life. As long as the microwave oven is used correctly, it will not cause harm to the human body.
