In fact, many people around us are worried about the use of household appliances, but I am afraid that the microwave oven is the most worrying. There are many terrible legends about microwave ovens. After listening to it again and again, it seems to be "common sense". Hearing these terrible rumors, Martin could not sit still. In order to reassure everyone, we must correct the name of the microwave oven today. Can microwave heating cause cancer? Many people will question the microwave oven, mainly because they have heard that it will produce "radiation". ?

As for auditory radiation, everyone thinks that it can cause cancer, but in fact, many electrical appliances such as radios and televisions emit radiation. In essence, sunlight is also a kind of radiation. The only difference between them is the frequency. Radio waves and visible light do not cause cancer, and microwaves with frequencies between them naturally do not cause cancer. In fact, the "radiation" mentioned here only refers to the energy of microwaves that can be emitted. It is different from the radiation produced by X-rays and radioisotopes. ? Although X-ray is also an electromagnetic wave, its frequency is much higher than that of microwave, so its energy is also very high. Radioisotopes will release particles in the process of decay, which will make organisms cancerous. Microwave will not cause human cancer, and food will not produce carcinogens. Even, it helps to avoid carcinogens. For fish, meat and other foods, traditional heating methods, especially roasting, roasting, frying and so on. It is easy to cause the meat to burn, thus producing some carcinogens. ? A scientific review published in 2004 introduced the generation and carcinogenicity of these carcinogens, and concluded that microwave heating can effectively reduce the generation of these carcinogens. ?

Is microwave harmful to health? Scientists have done a lot of research for us to find the minimum microwave power that can cause harm to human body. In a perfect microwave oven, the leaked microwave power is far from harmful to human body. The United States stipulates that the power per square centimeter should not exceed 5 milliwatts at a distance of about 5 centimeters from the microwave oven; The domestic standard is relatively strict, which is 1 MW. Moreover, the energy of microwave is attenuated according to the square of distance, and the amplitude of this attenuation is quite large. For microwave ovens that meet Chinese national standards, 5 cm radiation is harmless to human body, and 50 cm radiation is similar to natural radiation in nature. Therefore, for microwave ovens, as long as they are qualified products and are not damaged during use, they will not leak microwaves harmful to human body. So the microwave oven is actually quite safe for pregnant women and children.
