First, the harm of electromagnetic waves
1, harm of induction cooker, that is, harm of electromagnetic wave, measured data of induction cooker radiation:
According to experts in electromagnetic radiation in the industry, at present, the electromagnetic radiation intensity leaked by induction cookers at work has exceeded the human body's tolerance. For example, the measured data of leakage electric field radiation of an induction cooker of a certain brand is 1 13V/M, which exceeds the national standard GB8702-88 "Regulations on Electromagnetic Radiation Protection", and the public exposure to radiation cannot exceed? Several times of 40V/M; ? Measure the leakage magnetic field radiation value of the same brand induction cooker as 22.5μT? For magnetic field radiation, there is no corresponding electromagnetic compatibility standard in China's induction cooker standard, but the reference value of no more than 3-6μT in the control line is several times higher.
Mechanism of electromagnetic wave endangering human body
The mechanism of electromagnetic pollution endangering human body is mainly thermal effect, non-thermal effect and cumulative effect.
Thermal effect: More than 70% of the human body is water, and water molecules rub against each other after being radiated by electromagnetic waves, which leads to an increase in body temperature, thus affecting the normal work of internal organs.
Non-thermal effect: There are weak electromagnetic fields in human organs and tissues. Once disturbed by the external electromagnetic field, the weak electromagnetic field in equilibrium will be destroyed and the human body will be damaged.
Cumulative effect: Thermal effect and non-thermal effect have cumulative effect on human body, and the degree of injury will accumulate with time and influence, and will become permanent pathology over time. For people who have been exposed to electromagnetic radiation for a long time, even if the power and frequency of electromagnetic waves are very low, unexpected lesions may be induced.
2, the harm of electromagnetic waves
1998 a survey by the world health organization shows that electromagnetic radiation has five major effects on human body:
(1) electromagnetic radiation is one of the main causes of cardiovascular disease, diabetes and cancer mutation.
(2) Electromagnetic radiation will directly harm human reproductive system, nervous system and immune system;
(3) Electromagnetic radiation is one of the inducing factors of abortion, infertility and teratogenesis in pregnant women.
(4) Excessive electromagnetic radiation directly affects the development of children's body tissues and bones, resulting in decreased vision and liver hematopoietic function, and in severe cases, retinal detachment;
(5) Electromagnetic radiation can make male sexual function decline and female endocrine disorder.
Second, the harm of electromagnetic oven radiation
Men are particularly healthy.
Once many women who are engaged in IT industry have miscarried and become infertile, they will first attribute the cause to the computer. Experts pointed out that this is likely to "raise" the power of electromagnetic radiation too much, ignoring other reasons.
Electromagnetic radiation may indeed affect the human reproductive system, but it is mainly manifested in the decline of male sperm quality, because male germ cells and sperm are more sensitive to electromagnetic radiation. Therefore, men should try to reduce too frequent and intensive contact with electromagnetic waves, and keep a safe distance when contacting, generally more than half a meter.
Electromagnetic radiation and electromagnetic pollution are actually two concepts. Although electromagnetic radiation is everywhere, electromagnetic pollution will have a negative impact on the human body only after the electromagnetic radiation exceeds a certain intensity, leading to symptoms such as headache, insomnia, memory loss, rising or falling blood pressure, and cardiac borderline abnormality. If you work in an environment with excessive electromagnetic radiation for a long time, it may seriously lead to abortion, cataracts and even cancer in some people.
There is no epidemiological investigation to prove the influence of electromagnetic radiation on human body. Now everyone lives in an electromagnetic environment, but due to individual differences, the sensitivity to electromagnetic waves is different and the impact is different. Except for pregnant women in the first three months of pregnancy and special people with pacemakers, the general population need not worry too much, as long as they pay attention to general protection.
Electromagnetic radiation will have a series of biological effects on people. In the frequency band of 150 ~ 1200 MHz, it can penetrate more than 2 cm into the human body, stimulate the deep cells of the body, make them rub against each other to generate heat and interfere with the bioelectric current of the body itself. Electromagnetic energy is converted into heat energy in the body, resulting in imbalance of human thermal balance; Can cause "microwave cataract"; Destroy the spermatogenic ability of testis, leading to infertility; Cause changes in cardiovascular function. Children's nervous system is very fragile. If exposed to strong electromagnetic radiation, their brains will develop slowly and their biological clocks will be disordered. For pregnant women, it is easy to cause miscarriage, premature delivery and even fetal malformation.
Third, how to avoid electromagnetic oven radiation
1, when choosing an induction cooker, choose an induction cooker with relatively good quality. Don't neglect its quality just because it is cheap. Generally, the quality of well-known brands of induction cookers is guaranteed, and it is safer to use.
2, in the process of using the induction cooker, should not be too close to the induction cooker, should keep an appropriate distance, too close to the human body will be more electromagnetic radiation, when using the induction cooker, it is best to keep a distance of more than 40 cm.
3. When using induction cooker, the choice of cooker is also very important. Cookware made of copper, iron and other materials can absorb certain electromagnetic radiation during use, reduce the leakage of electromagnetic radiation and better protect the health of users.
4. To use the induction cooker for a long time, you need to choose an induction cooker covered with a metal partition. Putting the induction cooker under the metal partition can effectively reduce the radiation of the induction cooker and prevent the radiation leakage of the induction cooker. The radiation leakage of induction cooker with metal partition is relatively small.
5, in the process of using the induction cooker, try to reduce the use time of the induction cooker. Although the edge radiation of induction cooker is small, it is easy to hurt the body when exposed to radiation for a long time.
6. When using the induction cooker, you can use some anti-radiation tools, such as anti-radiation aprons or gloves, which can also effectively prevent radiation.
After reading the above introduction, everyone must be very familiar with the radiation hazards of induction cookers. Don't think that ordinary household appliances are harmless, and don't think that the quality of big-name products is guaranteed. Although it is more reliable, there will still be radiation over time. Therefore, it is suggested that everyone must leave more than half a meter when using the induction cooker. So much for the introduction of radiation hazards of induction cookers. Want to know more, please continue to pay attention to Tuba rabbit decoration!
