How to detect electromagnetic radiation by yourself? Induction cookers are used more and more widely, and almost more and more families use induction cookers. It is very simple to detect electromagnetic radiation by yourself. Let me see with you how to detect electromagnetic radiation by myself.
How to detect electromagnetic radiation by yourself 1 Electromagnetic radiation detector can detect electromagnetic radiation at home and workplace. Hold the electromagnetic radiation detector in your hand, aim the "test area" at the object to be measured, and slowly approach the object until it actually touches the object. The closer to the measured object, the stronger the electromagnetic field or electric field and the faster the alarm frequency.
In the measurement, the maximum reading can be obtained by changing the angle and position of the object to be measured as much as possible.
Long-term exposure to electromagnetic radiation will also affect and destroy the original bioelectric current and magnetic field of human body, making the original electromagnetic field in human body abnormal. Old people, children and pregnant women are sensitive to electromagnetic radiation, and their reactions will be particularly strong.
Is there any way to detect room radiation?
Generally, local disease control institutions, environmental monitoring stations or occupational disease monitoring institutions have special on-site detection instruments, which can detect indoor radiation levels.
The easiest way is to use the radio, turn off all the appliances in the house, turn on the radio, preferably multi-band, and choose a few bands to go back to no station (no signal) to listen to the noise. Noise means radiation, and vice versa. The comparison method is indoor and outdoor.
Tips:
The word "home appliance mountain" can be used at home. A mountain of household appliances has also brought a mountain of radiation. You want to know whether the radiation around you is safe. I suggest you use a radiation detector to measure it, which can clearly show the radiation dose value of the current site.
How to detect the harm of electromagnetic radiation 2 electromagnetic radiation to human body by yourself
Harm 1, which may lead to mental retardation of children. According to the latest survey, among the 20 million children born every year in China, 350,000 are disabled children, of whom 250,000 are mentally retarded. Some experts believe that electromagnetic radiation is also one of the influencing factors.
Hazard two. This is probably one of the causes of childhood leukemia. Medical research shows that long-term exposure to high electromagnetic radiation will cause changes in blood, that is, lymph and cell protoplasm.
Hazard 3. It can induce cancer and accelerate the proliferation of cancer cells in vivo. Electromagnetic radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, seriously induce cancer and accelerate the proliferation of cancer cells in vivo.
Hazard 4. High-dose electromagnetic radiation will also affect and destroy the original biological current and biological magnetic field, resulting in abnormal electromagnetic field of human body.
The influence of electromagnetic radiation on people;
The effects of electromagnetic radiation on human body include thermal effect, non-thermal effect and cumulative effect.
Thermal effect. More than 70% of the human body is water. Water molecules rub against each other through certain intensity of electromagnetic radiation, which heats up the body, thus affecting the working temperature of internal organs.
There are non-thermal effects and weak electromagnetic fields in the tissue. They are stable and orderly. Once the interference intensity of external electromagnetic field is too large, the weak electromagnetic field in balance will be affected or even destroyed.
Cumulative effect. After thermal effect and non-thermal effect act on human body, if the influence on human body has not yet reached self-recovery, and it is affected by excessive electromagnetic radiation for a long time, the degree of influence will accumulate, and cumulative effect will be formed over time.
It has been proved that if the radio frequency electromagnetic radiation reaches a high enough level, it can heat biological tissues and cause potential damage, mainly because the human body can't bear the excessive heat generated.
Electromagnetic wave transmission mode:
Electromagnetic waves are absorbed by the body through energy. When the human body is under the radio waves of mobile phones and base stations, most of the energy will be reflected or bypassed by the human body. But some energy will be absorbed by human epidermal tissue.
Due to the appearance of electromagnetic field, some molecules in the body will start to move or rotate. Through "friction", energy is converted into heat. If the radio wave density is high, the heat may be large, which may cause some harm. The energy used by mobile communication system is very low, so the heat generated by skin absorbing radio waves will be very small and will not be detected.
How to detect electromagnetic radiation by yourself? What are the hazards of electromagnetic oven radiation to 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, leading to the decline of vision and liver hematopoietic function, and in severe cases, it can lead to retinal detachment;
5, electromagnetic radiation can make male sexual function decline, female endocrine disorder.
In fact, the harm of induction cooker mainly comes from electromagnetic radiation. Although the radiation frequency of induction cooker is only one sixtieth of that of mobile phone signal, its radiation power is much larger than that of mobile phone signal. The radiation power mainly depends on the electromagnetic wave leakage value of the induction cooker, and the greater the leakage, the greater the harm to users! Long-term or long-term use will have a greater negative impact on human health.
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.
When buying an induction cooker, you must choose a regular well-known brand. Generally speaking, the more formal the induction cooker, the stricter the production and the smaller the relative electromagnetic radiation. In addition, when choosing a pot, it is mainly made of steel products, which can reduce its leakage. When buying an induction cooker, ask the seller for the test report of electromagnetic induction intensity. Generally, induction cookers have this thing. By comparing this report, you can choose an induction cooker with relatively low electromagnetic radiation.
