In fact, many people around us have concerns about the use of household appliances, but they are probably the most concerned about microwave ovens. There are also many scary legends about microwave ovens. Everyone has heard it over and over again, and it seems to have become "common sense." Hearing these terrible rumors, Ding's mother couldn't sit still. In order to make everyone feel at ease, the name of the microwave oven must be corrected today. Does microwave heating cause cancer? Many people question microwave ovens, mainly because they have heard that microwave ovens produce "radiation". ?
When they hear about radiation, everyone thinks it can cause cancer, but in fact many electrical appliances such as radios and televisions emit radiation. In essence, sunlight is also a form of radiation. The only difference between them is frequency. Radio waves and visible light do not cause cancer, and microwaves with frequencies between the two 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 radioactive isotopes. ? Although X-rays are also electromagnetic waves, their frequency is much higher than that of microwaves, so their energy is also very high. Moreover, radioactive isotopes will emit particles during the decay process, which can cause cancer in organisms. Microwaves do not cause cancer in humans, and food does not produce carcinogens. Even, it helps avoid the production of carcinogens. For fish, meat and other foods, traditional heating methods, especially grilling, roasting, frying, etc., can easily cause the meat to burn, thus producing some carcinogens. ? A scientific review published in 2004 described the production and carcinogenicity of these carcinogens and concluded that heating in a microwave oven can effectively reduce the production of these carcinogens. ?
Are microwaves harmful to the body? Scientists have done a lot of research for us to find the minimum microwave power that can cause harm to the human body. In a perfect microwave oven, the leakage of microwave power is far from enough to cause harm to the human body. The regulations in the United States are that the power per square centimeter should not exceed 5 milliwatts at a distance of about 5 centimeters from the microwave oven; while our country's standard is more stringent, which is 1 milliwatt. Moreover, the energy of microwaves weakens according to the square of the distance, and the amplitude of this weakening is quite large. For microwave ovens that meet Chinese national standards, 5cm of radiation is harmless to the human body, and 50cm of radiation is almost the same as 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 that are harmful to the human body. Therefore, microwave ovens are actually quite safe for pregnant women and children.
